Well, then it's easier to tell somebody to do a

$ python -c "import _ldap"

to track down problems.

Another issue I forgot to mention so far is that I can't reuse
constants of _ldap if importing it fails. I have to define them
separately anyway.

Hmm, I think I will stick with a separate module package.

Ciao, Michael.
