Ok. I haven't really run into any problems there, but that may be
just because I haven't installed Gnome or KDE.

Symlinks can fix that, if you like. The idea is that files should be
*accessible* via their standard /package/... paths; they can be
*stored* however you like.

My whole system uses /package.

/package can always be available.

I see. The Right Way to handle this is to make sure each package is
properly maintained, so that they can all link to the latest version
of their dependencies.

That's already possible. Make the library's SONAME be its absolute
path. Or, if you want different programs to refer to the library via
different paths, then for each program, build a dummy library whose
SONAME is the (program-specific) absolute path of the real library you
want to link to. Then use that dummy library on the gcc command line
for linking. But I agree that it would be nice if ld had a
command-line option that says "link to this absolute path, ignoring
the SONAME stored in the library".
