Please find attached ghostscript-6.50-r4.ebuild. This additionally patches the ghostscript sources so that the HP developed HPIJS drivers may be used (giving an ijs device if you use gs -h). People will still need to compile the HPIJS server but this is an easy ./configure, make, make install. I can write an ebuild if you like. I haven't run through the new ebuild using emerge but all the individual steps work.

OK, I don't know what HPIJS is but I added it. Thanks for the ebuild! Sure, it would be great if you could write an ebuild for the HPIJS server.
