I'm encountering the following problem when trying to build gpsd-9999:

MAKEOPTS="-j1" ebuild /usr/portage/sci-geosciences/gpsd/gpsd-9999.ebuild compile

I've reported the issue and proposed a patch on the gpsd-dev list a while ago, but unfortunately recieved no answer:

well, it's an ebuild that builds live upstream code, so if upstream's code is broken, the answer is to go through them.  we don't carry patches in live vcs ebuilds to fix their problems because we aren't upstream.
