# LUA_HOME    ... where to find lua header and library files

# If this is a local build, then you should set the environment variable
# LUA_CPATH to the local directory. On bash, this will work:

# export LUA_CPATH="$LUA_CPATH;`pwd`/lib/?.so"

# Absolute paths may be used instead, which will be useful if you are doing a
# remote install.
