Comment 1 for bug 919147

I would be willing to merge a branch which added a tested feature for your
use case.

For instance, if all the "normal" candidates fail, you could look for a
'setup.py' in the original path: if present, you could create a
tempdir, and then run 'python setup.py egg_info --egg-base=/path/to/tempdir'
in a subprocess: the 'tempdir' would then contain the '*.egg-info'
directory.
