I believe that this problem occurs when aggdraw (and probably PIL) are
built without freetype2 support. Try installing the development
packages for freetype2 on the new machine and then rebuilding aggdraw.
Check through the output of the aggdraw build to make sure that it's
actually finding the freetype libraries.
Hope this helps,
