No worries. Grad to see we're at least seeing the same thing (this has been a very elusive bug...) I submitted a fix for this in matplotlib SVN r4047. Freetype takes a FT_LOAD_FORCE_AUTOHINT flag to force it to bypass the patented bytecode hinter at runtime (even if it was compiled in). This appears to fix the problem, and doesn't force people to recompile their freetype -- they should now get identical results regardless.
