In the gnome overlay app-text/gtkspell-3.0.0_pre20110814:3 is available. Pidgin does not build against this, only gtkspell-2.*. This can be solved by depending on the slotted version. Reproducible: Always Steps to Reproduce: 1. emerge gtkspell-3 2. unmerge gtkspell-2 (depclean) 3. emerge pidgin (preserved-rebuild) Actual Results: ... checking X11/SM/SMlib.h presence... yes checking for X11/SM/SMlib.h... yes checking for GTKSPELL... no no configure: error: GtkSpell development headers not found. Use --disable-gtkspell if you do not need it. ... Expected Results: Build finishes successfully. I know this issue is caused by the gnome-overlay, but this ebuild will hit the portage tree one time. So it is better to be prepared.
