Slashpackage <URL:http://cr.yp.to/slashpackage.html> offers a
solution.  Let each version of each package be installed in its own
directory, and let each package find its dependencies via symlinks
kept in its own directory.
/path/to/A-1.0
/path/to/A-2.0
/path/to/B-*/deps/A -> /path/to/A-1.0
/path/to/C-*/deps/A -> /path/to/A-2.0

In the common case, the symlinks wouldn't need to single out a
specific version, so they could just point to /path/to/A, which is a
symlink to the "current version" of A.
