exec: wish8.0: not found

[Jeff Hamann]

when I attempt to execute some of the grass commands like r.report
they aren't available. why? is there a way to check to make sure
all the file compiled and installed correctly? And what is wish8.0?
is it something I need to download. how do I compile to files in
src.alpha? 

Thanks,
Jeff.
