You mean you are using the sample nsd.txt (that should be renamed to nsd.tcl) that comes with the OpenACS documentation? In the docs I specified what to do with your AOLserver install if you were using our nsd.txt.
You probably missed somelines or you did not specify the AOLserver home in the nsd.tcl (should be in the beginning of the file). If you have it here, then AOLserver looks for the standard tcl library at $HOME/servers/$servername/modules/tcl.
Many people have been using the included nsd.txt without problems (including me) as long as they follew the documentation. Did you check the AOLserver Simple Install Guide (part of the OpenACS docs)?
