All you have to do to fix this is to add "-ldl" to the gcc command line,
and it will get past this.  This is from the newer TCL's dynamic object
loading functionality, which requires libdl.so.

This I'm not sure about, but it does have something to do with your tcl
installation.  If you've installed your own tcl7.6 and tk4.2, the stuff
will all be below /usr/local (If you used the defaults).  Problem is,
you've probably still got the original redhat installation in there, which
goes in /usr/lib/tcl* or /usr/lib/tk*.  Try running the command 

locate init.tcl

and see how many you have and where they are.  


Hope this helps!
