First check and make sure you really want to remove the package;
rpm -e tcl --allmatches --test
See anything you want to keep, if no do the next level of checking;
rpm -e tcl tcl-devel tclx expect tx dejagnu --allmatches --test
Repeat until the results come back clean, then you can remove the --test switch and remove the packages.
You can do the same thing with yum (or the GUI[s] to; Kyum and/or yumex) if installed.
