net-libs/xulrunner-1.8.1.14 fails to compile if x11-libs/pango (1.20.3) is built with USE="-X": [...] nsDeviceContextGTK.cpp:70:26: error: pango/pangox.h: No such file or directory gmake[4]: *** [nsDeviceContextGTK.o] Error 1 [...] recompiling x11-libs/pango with USE="X" fixed the issue. please add a test if pango was compiled with USE="X" to xulrunner. [ this probably also affects 1.9 series of xulrunner ]
1.9 was fixed already Fixed on 1.8, thanks for the report
