Forum OpenACS Q&A: Response to Using [incr Tcl] with AOLserver

Aolserver has its own tcl interpreter compiled in, and there are some well-known problems with using package require in Aolserver/Tcl. See this thread for a work-around. You might also try searching the bboards to see if you can find out if anybody has successfully used [incr tcl] with aolserver. I know that Xotcl has been used successfully with aolserver. See this thread for more details.
