As pointed out in bug #74561, x11-libs/fox is using a local freetype flag (which is then used by xft switch), instead of the global truetype flag. I took time to clean up the ebuild, using econf instead of ./configure and adding missing use-flag, as well as renaming freetype useflag to truetype. HTH, Diego
