tcltkgrass error

Hi,

I am attempting to get tcltkgrass2.3 to run under SuSE 5.3 Linux. I
installed Grass 4.2.1 and it runs correctly. I then installed the Linux
version of TclTK8.0 following the instructions (although I originally
extracted the package in /tmp instead of /). I then installed TCLTKGRASS
2.3 following the instructions.

However, when I run tcltkgrass, I get the following error message:

loading...
wish8.0: can't load library
'libtk8.0.so'
/usr/local/bin/tcltkgrass: GISDBASE: parameter null or not set

What did I do wrong?

Thanks,

-Steve
