Yes, it would. I was too sleepy when I wrote that.
I have Etch aka testing aka 4.0 (iirc).

It was installed in the debian-way via apt-get/aptitude, version is
1.1.5-11.

Oddly enough it works when I start genmap explictly with python-2.3
instead of 2.4, so I'll try to fall back to pyhton2.3.

I change the shebang lines of all the python scripts to
#!/usr/bin/python2.3
and when I run ./genmap from the command line I get the desired output
(Content-Type: image/png, an empty line + binary data, which _is_ a
png), but over the web server I still get the same errors.

Is fastcgi somehow using a different interpreter from the one specified
in the #!-line? (And yes, I restarted apache2 after changing the
interpreter).


Thanks again,
Moritz
