>Description:
The math/open-axiom port seems broken. I tried a few things from an Axiom tutorial I found, but got poor results.

As I understand it, both of the exponentiation computations should have given a result as a big integer. Indeed, this is what happens with original Axiom on a Linux system. Instead the first one gives a floating point overflow and the second causes open-axiom to exit.
It is possible this is just a situation of open-axiom behaving differently from classic Axiom, but it seems unlikely. It could also be an amd64 related problem; I have not tried it on i386.
