""" Some helper functions for building the C extensions you may need to edit basedir to point to the default location of your required libs, eg, png, z, freetype DARWIN I have installed all of the backends on OSX. Tk: If you want to install TkAgg, I recommend the "batteries included" binary build of Tcl/Tk at http://www.apple.com/downloads/macosx/unix_open_source/tcltkaqua.html GTK: I installed GTK from src as described at http://www.macgimp.org/index.php?topic=gtk. There are several packages, but all configure/make/make install w/o problem. In addition to the packages listed there, You will also need libpng, libjpeg, and libtiff if you want output to these formats from GTK.
