Or rather, courtesy of the default path.

No problem.

Strange. If at all the symlink should be

/usr/lib/gnumed-server/Gnumed -> /usr/lib/gnumed-server/server

But actually, assuming the proper version of the Python
modules are in /usr/lib/python2.5/site-packages/Gnumed/, no
such symlink should be needed at all.

You can verify proper system-wide installation of
gnumed-common by opening a console, typing "python" to start
an interactive session and typing

        "from Gnumed.pycommon import gmTools"

If that works the modules see properly installed.

*IF* you want to make the bootstrapper use local modules,
then, yes, prepend "/usr/lib/gnumed-server/" to PYTHONPATH
(note the missing "server" directory).

It does try to set things up:

snip
        cd ../../
        ln -vsn client Gnumed
        cd -
        export PYTHONPATH="../../:${PYTHONPATH}"
snip

which will only work if the scripts are invoked locally from
server/bootstrap/:

        cd server/bootstrap/
        ./boostrap-latest.sh

If that doesn't work something is rather odd.

It must point to the directory which *contains* the top
level package name == directory, IOW "Gnumed".
