nothing working after solaris/bin installation

Dear friends

I installed yesterday the following patchs of grass4.1:

  g.5.cpio.Z.*
  sol.4.tar.Z.*
  xg.5.cpio.Z.*

I configured all thing (including environment variables), but
only somethings are working like start/stop/erase an X display,
use the help. But, when I try run grass commands the system
remain stalled. Below follow some commands that I tryed:

  $ r.mapcalc x=1 # the system display 100% and stop
  $ r.support # I can see the list of image bands
        but when I select one of them the
        system stop to

All stopping don't display error messages, just don't go!

Sorry for do it so trouble, but I can't solve it without
your helps!

Cheers,
