a)
supertux2 is on repository 'free', so it should contain source code. This is not the case. Source file in page:
http://maemo.org/packages/source/vie...rtux2/0.3.3-3/
(same file which you get with 'apt-get source')
is not source code, but compiled binary.

-> Package must contain source code or be in 'non-free'-repository.

b)
Doesn't matter is it in 'free' or 'non-free', it is GPL and there must be according sources published/offered.
Where are source code used to make debian-package?


I would suggest uploading source code to the autobuilder (for 'free'-repository) and you will comply everything.
