Can't find TclX

[Paul C. <pj...@no...>]

I have three questions:

Question 1:
===========
Where do you get TclX?
Their old download site doesn't work.
ftp://ftp.neosoft.com/pub/tcl/TclX/
and neither does the Sourceforge download site
http://sourceforge.net/projects/tclx
http://sourceforge.net/project/showfiles.php?group_id=13247

Question 2:
===========
What's the "correct" version of TclX to use?

When I try to use TclX-8.0.2 I get the following error:
# make
gcc -o modulecmd -L/usr/local/lib   -L/usr/openwin/lib -R/usr/openwin/lib
-R/usr/openwin/lib:/usr/local/lib -g ModuleCmd_Avail.o ModuleCmd_Clear.o

ld: fatal: Symbol referencing errors. No output written to modulecmd
collect2: ld returned 1 exit status
make: *** [modulecmd] Error 1

Question 3:
===========
I can compile without TclX, but then I don't get the
interface "module" (the main command). I have "modulecmd"
but not "module". Is this interface command dependent on TclX?

Thanks,

Paul
