Agreed, all this is a configuration management problem. It is far better
in my view to have some kind of script that configure the software
before compilation. This script will check the OS for example and use
the proper bodies for some of the OS specific packages. This is exactly
was the ./configure & make does on most software. I think it is wrong to
try doing that with the language itself. As pointed out there it can
work in some very simple case but it won't generally.
