Description of problem:
Tcl searches a set of directories to find installed extensions.  These
extensions are loaded using Tcl's "package require foo" command.  On
FC2-x86_64, /usr/lib64 needs to be part of this default list of
directories.  Currently this is preventing the TclX extension from
being loaded:

# tclsh
% package require Tclx
can't find package Tclx
% lappend auto_path /usr/lib64
% package require Tclx
8.3

Version-Release number of selected component (if applicable):
tcl-8.4.5-7

How reproducible:
Always

Steps to Reproduce:
1. start tclsh
2. type "package require Tclx"

    

Actual Results:  Tclx fails to load with "can't find package Tclx"

Expected Results:  Tclx loads and reports its version "8.3"
