Description of problem:
The /usr/X11R6 heirarchy was removed from filesystem in 2.3.7-1, but setup
2.5.47-1.1.1 still adds /usr/X11R6/bin to PATH variable.

Version-Release number of selected component (if applicable):
setup-2.5.47-1.1.1

How reproducible:
Everytime, see below:
a) open a bash for example and "echo $PATH"
b) do a "grep -r X11R6 setup-2.5.47"

Actual results:
/usr/X11R6/bin in PATH variable.

Expected results:
No /usr/X11R6/bin in PATH variable ;-)

Additional info:
I'm not sure, whether the new if-statement in my small patch is correct...
