Please be sure your the .bash_profile text file has the usual paths as well as the one you want to add.
Like /usr/bin /usr/local/bin, if it is corrupted you may want to reinstall bash(delete or rename your ~/.bash_profile) to repair it.
If the file is intact, I suggest you post on the grass forums. Google is your friend.
Only other thing I can think of is ldconfig and symlinks.
run man for symlinks and ldconfig to see what they do.
Generally I use
sudo symlinks -csrv / && sudo ldconfig -Cfrv
This will check the links (shortcuts) for your system and update stale ones and drop dangling links.
