Boytcho,
Are you following the OpenACS 3.2.5 documentation? We have a pretty detailed Installation Guide, and also a sample nsd.tcl (AOLserver configuration file).
If you followed that guide and can't get it to work, I would appreciate you tell me at what step of the guide did the installation fail.
The documentation (and sample nsd.tcl file) are at https://openacs.org/doc/(and in the /doc/ directory of your OpenACS distribution).
