After I have installed the package I was not able to call the command 'mdoule' as described in the documemntation. You have a man page 'module' but the a file 'module' on /usr/bin. Instead I have fount the file 'modulecmd' on /usr/bin.
Did you get a new shell after installing? /etc/profile/modules.{csh,sh} should set up your environment so you have access to the module alias.
No, Thank you for the hint. After I have logoned again it's works as accepted.
perhaps it may be make sense to have a postinst script in the package.
