I synced the science overlay at revision 1038 (it includes change 1036 relating to the same issue apparently) and tried to emerge udav it fails with the following message: checking for mgl/mgl_c.h... yes checking for main in -lmgl... yes checking fltk-1.1/FL/Fl_Export.H usability... yes checking fltk-1.1/FL/Fl_Export.H presence... yes checking for fltk-1.1/FL/Fl_Export.H... yes checking for main in -lfltk... no Please install FLTK library (libfltk) --------- I have fltk-1.1.7-r2 installed.

Ok as it happens libfltk is in /usr/lib/libfltk-1.1 and the configure program as it is with the patch cannot find it. After inspecting a few ebuild including fltk (cupsddk fltk patch was especially instructive) I decided to change things a little bit. So here is an updated patch and ebuild which build on my system. mathgl has the same problem and could use the same kind of love. I may do that if I have time.
Created attachment 152805 [details, diff] new fltk patch for udav
Created attachment 152807 [details] revised ebuild using the new patch Sorry a bit too lazy to diff that one.
Thank you, your solution is very nice. I applied it (together with a few more improvements), and also wrote something similar for mathgl (though there things are a bit more lengthy).
Not to be a pain but it compiles and run on my ppc machine, can you keyword them ppc as well?
