IMHO ideally pkgsrc would be able to build/install various gcc versions
as well, with different paths, and could switch them, and extend that
switching to select among both DragonFly base system compilers.

I think so far the pkgsrc reaction has been to patch the offending
packages, but that may be hard.  I know I haven't gotten around to
fixing cfs which is in the same boat.
