A pretty widespread Linux distribution.
Jeff Hobbs warned in the Tcl chatroom on 2003-05-20: "for reference for anyone else here, RH9 sucks, and sucks especially for what they did to Tk on it. Do not use the RH9 default Tcl/Tk install."
What exactly did they do to it? - davidw
Good alternatives are Debian and Suse.

Is there any mysterious reason why RedHat do not use Tcl8.4 but still Tcl8.3 (RedHat 9)? It is the only reason why I distribute my tcl programms still in Tcl8.3 version. Suse use Tcl8.4 for long time. Do not tell me about stable versions. Suse is also stable with Tcl8.4.
It seems that Suse support Tcl better than RedHat. Suse 8.2 distribution have special package managment point (Tcl-Development) and have also vtcl and SpecTcl as RPM packages.
