So far, only Tcl 8.4.* is supported by OpenACS. Most of the installations use Tcl 8.4. Version 8.4.19 is recommended.
One should however note, that some Linux distributions come already Tcl 8.5 (e.g. Fedora 9), so it is good to know that this will work as well.
From the other thread, i had the impression by specifying the tclsh, everything worked well for you...
