Because of this (./configure --without-gimp-print), my printer's driver does not work. I think gimp-print should be forced as dependency for ghostscript, or at least it should depend on a new USE flag named "gimp-print" Reproducible: Always Steps to Reproduce:
--without-gimp-print only disables stp drivers. there is an identical ijs driver in the gimp-print package for each stp driver, so this is no problem.
Well... it is a problem. My printer's ppd taken from foomatic (Epson Stylus C62) use gv -sDEVICE=stp. Anyway I don't see why disable stp in the first place. I did modified ghostscript ebuild on my computer so my problem is solved, but I think about other unfortunate printer users.
