Strange sclang problem in scide

yes, it-s very unfortunate that scide seems to have no other options than -h.

i found two links that maybe could be helpful (under the assumption that it still might be a problem with the path variable):
https://help.ubuntu.com/community/EnvironmentVariables

a little old:

the other option would be to reinstall supercollider and hope that this will fix the problem.
