 For the project at hand we needed fast and simple drawing -- 8-bit color, no anti-aliasing.
 We also wanted a nice simple API to work with. There are a number of newer drawing libs (AGG, Skia)
 that produce some pretty results, but are not as simple to use, and are focused on 32 bit fully

 In order to build `py_gd`, the Cython package is also required: http://cython.org/
 
+Most critically, `py_gd` requires the `libgd` libary, which itself requires a number of other libs, such as `libpng`, `libjpeg`, etc, etc...

 In a word: no.
