upgrade issue - can't log in

[david <..hidden..>]

I'm upgrading from Ubuntu 8.04 LTS to 10.04 LTS.

First I cloned the old server using mondo to a virtualbox server, then 
did <apt-get dist-upgrade>. All services are working (with some 
tweaking), but I can't log into LSMB.

I'm suspecting a PERL problem, but would appreciate any pointers.

Postgresql is running.

Firefox gives me:

 Error message:
 Premature end of script headers: login.pl

Apache log:
