mercurial cannot be loaded, is there any difference when going from 2.0.0 to 2.2.x?

[solo turn]

hi,

we used to run mercurial hgwebdir.cgi on apache 2.0 (see
http://selenic.com/repo/hg/file/0c8a783dd197/hgwebdir.cgi).

recently we tried to do the same with apache-2.2 and it did not work any more.

from mercurial.hgweb.hgwebdir_mod import hgwebdir
produces "hgwebdir" not found or similar messages.

is there any change in setting the environment for cgi-scripts which
was not communicated so we got to know it too? because calling python
on the command line and then issue  the import there works fine.

or, could anybody running it on apache-2.2.X send the bin/envvars and
httpd.conf pls? maybe its just a little thing we overlooked.
