You can tell I'm used to working from source :)

As mentioned before, I'm looking into the autoconf/automake process.
They have a concept of DISTDIR which is prefixed to the install
path as in $(DESTDIR)$(bindir) (the default value of DESTDIR is "").

In theory, I can do a

  make install DESTDIR="blib/"

and it will install my package underneath:
  blib/usr/local/lib/python1.5/site-packages/kwyjibo/...
and my executable scripts under
  blib/usr/local/bin/melissa


Wouldn't it be possible to have distribution program figure out
what to do based on this tree, including knowing to make .pyo
and .pyc files from .py files, if they exist?

Of course, permissions are problematical here as well.  The
package generation program could have a hook which lets the
distributor add some python code to adjust things accordingly.
Also, I could use a special INSTALL program which doesn't actually
set the permissions but instead logs them to a file for the
packager (hook) to use.
