Just checking that I'm interpreting this correctly: if a user already has the libraries installed, they can leave the statements commented out, ONLY IF they're installed in the {EXTERNAL_LIBS} location. Otherwise, if they're installed somewhere else the user will need to uncomment the line and provide the correct path.
What should be done if the libraries aren't installed? Leave them commented out?

Yes.

if a user already has the libraries installed, they can leave the statements commented out, ONLY IF they're installed in the {EXTERNAL_LIBS} location.

If the libraries are commented out, the script will always attempt build the libraries in the external_libs directory. If the libraries are installed somewhere other than the external_libs directory and the user would like to use those libraries, they will want to uncomment the line and provide the path. If the libraries are installed in the external_libs directory and the user would like to use those libraries, they will want to uncomment the line and leave it as-is. If the libraries are not installed and the user would like the script to install them, they should leave the lines commented out.

Phew, that's kind of a mouthful, let me try to say it better:

Uncomment the external library variables if the libraries are installed in any location and the user would like to make use of those pre-installed libraries. If the libraries are in the external_libs dir, uncomment and do nothing. If the libraries are not in the external_libs dir, uncomment and change the paths to the appropriate location.

Leave the external library variables commented out if the user would like the library/libraries installed in the external_libs subdirectory.

That clears it up a bit, thanks. Given that truth, I would suggest a slight change to the wording to reflect closer to what you've just said,

If users have already installed these libraries and would like to make use of them, uncomment out the export statements. If those pre-existing libraries are in the external_libs directory, no further edits need occur; however, users that have the pre-existing libraries not in the external_libs directory will need to update the paths to the appropriate location.

Does that convey the necessary information well?

@j-opatz, yes that conveys the necessary information well. Thank you for simplifying it! I appreciate it!

I made one slight change to that wording the in the update to the documentation. Instead of "no further edits need occur", I said, "no further edits are needed". If you prefer the original wording that is fine, and please feel free to change it.

# compile them again, please comment out the export statements with a "#" symbol
# in front. If you have these installed in a location other than ${EXTERNAL_LIBS},
# you can provide the appropriate path below and uncomment the line.
#export EXTERNAL_LIBS=${TEST_BASE}/external_libs
#export MET_GSL=${EXTERNAL_LIBS}
#export MET_BUFRLIB=${EXTERNAL_LIBS}/lib

#export BUFRLIB_NAME=-lbufr
#export MET_NETCDF=${EXTERNAL_LIBS}/lib
# Also, don't forget to set the following options to zero within the compile script if you've already compiled those libraries as well: COMPILE_GSL, COMPILE_HDF, COMPILE_HDFEOS, COMPILE_CAIRO, COMPILE_FREETYPE
#export MET_HDF5=${EXTERNAL_LIBS}
#export MET_NETCDF=${EXTERNAL_LIBS}

# The optional libraries HDF4, HDFEOS, FREETYPE, and CAIRO are used for the
# following, not widely used tools: MODIS-Regrid, lidar2nc, and MODE Graphics.
# To enable the compilation of these libraries, set the compilation flags for
# the library (e.g. COMPILE_HDF, COMPILE_HDFEOS, COMPILE_CAIRO,
# COMPILE_FREETYPE) to any value in the environment config file. If these
# libraries have already been installed and don't need to be reinstalled, set
# MET_HDF, MET_HDFEOS, MET_FREETYPEINC, MET_FREETYPELIB, MET_CAIROINC,
# and MET_CAIROLIB to their installed locations
