Bugzilla Bug 197396

When attempting to emerge sci-astronomy/ds9, the emerge fails because somewhere
in the source makefiles, it assumes a default compiler name of 'gcc34' (and
g++34).  A simple patch to the ds9-4.13.ebuild file is attached which fixes
this problem.



Reproducible: Always

Steps to Reproduce:
1. Add 'sci-astronomy/ds9 to /etc/portage/package.keywords
2. emerge sci-astronomy/ds9

I'm unsure whether I should have the CC and CXX environment variables set, I
don't think I unset them anywhere.  I don't know if I should have a gcc-3.4
version installed, as it appears this is what ds9 expects.  I still think the
ebuild would be incorrect (and fail) anyway.  Here is my emerge --info:
