E.g. Like what Buildout does for you?

my_dir is not the destination it's the requirement_or_url e.g. 
Something with a setup.py in it.

I don't fully understand, but I expect this may be normal given the 
contraints above (i.e. easy_install does not understand what you intend 
by specifying "my_dir" AFAICT).
