mod_perl + any other DSO module returns no data

[Asghar Nafarieh]

I have a linux machine with ssl, php, mod_perl + apache 1.3.12.
If I load mod_perl module by idself it works fine. But if
I add any other module in conjunction with mod_perl in httpd.conf 
I get "document has no data". I used both mod_perl 1.21 and mod_perl 1.23 
with either perl 5.005_03 and perl 5.6.0 and I still get the same result.
I changed the apache to 1.3.9 and I still get the same result. 

Anybody has any answer?


Thanks,
