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 does not use Tcl8.4, but still distributes Tcl8.3 (in RedHat 9)? It is the only reason why I distribute my Tcl programs as Tcl8.3 versions. Suse has used Tcl8.4 for a long time. Do not tell me about stable versions. Suse is also stable with Tcl8.4.
It seems that Suse supports Tcl better than RedHat. Suse 8.2 distribution has a special package managment point (Tcl-Development) and has also Visual tcl and SpecTcl as RPM packages.
