Sadly, on Debian, the gdc packaging and the ldc packaging conflict over
the search path for module sources and so gdc will not work if ldc is
installed. 

This turns out to be a real ####### pain for the SCons tests.

The problem for Fedora is that there are no maintainers taking
responsibility for D stuff other than ldc. Like Debian and Arch, Fedora
relies on people volunteering and keeping going with packaging. ldc is
packaged by all, which is good. Sadly no dub.

I thought DMD and Phobos were separate. Given proper versioning (which
I think we have) there should be no problem.
