Enabling Xft in the fltk ebuild breaks the build, probably due to changes in the Xft part of Xfree 4.2.1. Removing --enable-xft from the ebuild script results in a successful build.
there's some changes coming to xfree's ebuild that should sort this out
fltk-1.1.2 is now in portage. It includes Xft-2.0 related fixes and many other bug fixes mostly in the fluid application.
Can you please test 1.1.2 and let me know if you still have xft related problems? Justin, are you still around?
Sorry, I can't really test this right now; thanks for looking into this!
fltk-1.1.2 has been marked stable.
