I have to admit I did not do these tests; I was experimenting with a borrowed machine, and I ran out of time. However, I have run nosetests on a build of master on Ubuntu 10.10, with freetype 2.4.2, and I see the same failure that you showed on the font_styles test. Same test on a build of v1.0.x, same failure. Fails for png and svg; passes for pdf, but the images being compared are ugly low-res bitmapped things. The major change between the freetype 2.3 series and 2.4 seems to be "In addition to many bugfixes, the TrueType bytecode interpreter is now enabled by default. All users should upgrade."
