-> No chance for us to ship Truecrypt with the current license. :-/

Since 2008-07-08 TrueCrypt 6.0a is available. Even if "TrueCrypt License 
Version 2.5" might be fine for us there seem to be packaging issues left. 
Either someone is investigating on this or we won't be able to ship truecrypt 
with the upcoming grml release.

I'm absolutely not happy with that situation, we have to check that before 
providing, shipping and releasing a new truecrypt Debian package.
