Thanks for the clarification. Let me restate it to check I am having
it right. You have a poset, say:
sage: P = Poset((divisors(30), attrcall(divides)))
and then you want to manipulate a bunch of linear extensions of that
poset like::
sage: l1 = [1, 5, 3, 2, 10, 6, 15, 30]

One of the main points of the gcc spkg is because llvm-gcc is buggy,
clang should be just as able to build gcc, and doesn't suffer from the

I have added a new version, with an implementation of finitely
presented groups.
It can be improved for sure: lots of gap functions can be wrapped, and
maybe the implementation is not optimal; but it works. It passes all
the test suite except the pickling tests. Any clue about how to solve
it?
