  I have a few "Suggests" in sagemath.spec for packages I added to
non-free, but I packaged only what is required to run "sage -testall"
plus a few extra optional packages, and run the optional tests as well.

  But I would not be surprised if there are some packages with not
truly open source license, or unmet special conditions; but they
are only available from "contrib" mirrors, and upstream tags them
as GPL, BSD, etc, but I did not fool proof read every license...

  Major problem should be integration of all components. There
are few cases where it is required some patch to a package
that is not only a sagemath requires. Most intrusive AFAIR
are ntl patches.

  Some components really require a specific version, what may not
be easy to achieve either, but so far, for Mandriva besides a
PYTHONPATH with several patched components, for sagemath 4.8,
most notably is use of a custom cython and ipython. Should work with
current system cython, but that depends on the stage of the moon
(if cython is updated) :-), there is only one binary in PYTHONPATH
(cPickle.so) that I have been carrying for quite some time,
http://bugs.python.org/issue7689
and generating it by doing a build of python in sagemath build.

  Sometimes some problems are very specific to the package, what may
be hard to track, like this one
http://code.google.com/p/gmpy/issues/detail?id=49
or some other earlier related issues with sympy having its own copy
of mpmath, and then having conflicting modules loaded.
