Install advice?

[Mark Ungrin]

Hi and thanks very much. I have been working on the setup -
unfortunately I'm new to WSGI as well so that's added some speed bumps
as well.

I have apache2 working with WSGI now, with the following outcomes:

(my files are in /var/www/slidetest/)

when I go to the web site and specify /slidetest/ I can see the
directory listing

when I go to /slidetest/myapp.wsgi, it does what it is supposed to
("Hello world"), so WSGI is apparently set up OK
when I go to /myapp, which is aliased to /slidetest/myapp.wsgi, it also
works, so I assume this means aliases are not the problem
when I go to /slidetest/deepzoom.wsgi, (directly or via an alias) I get
"Internal Server Error..." and the generic "contact the server
administrator" message

the code is this file is:
>
> import os, sys
> from deepzoom_server import app as application
> application.config.update({
>     'DEEPZOOM_SLIDE': '/var/www/slidetest/openslide_testdata/CMU-1.svs',
> })
>

...and now I'm kind of stuck. Any suggestions on what to try next?

thanks

Mark
