Comment(by fbissey):
I have boldly pushed it to the sage-on-gentoo tree and can report that it
works fine with python-2.7.1 there on 4.7.1.alpha2. It solved the problem
we had but another doctest crashed that looked completely unrelated until
I looked at the backtrace:
{{{
sage -t -long -force_lib devel/sage-main/sage/crypto/mq/sr.py #
Killed/crashed
}}}
and here is it says when I add -verbose
{{{

------------------------------------------------------------------------
Unhandled SIGSEGV: A segmentation fault occurred in Sage.
This probably occurred because a *compiled* component of Sage has a bug
in it and is not properly wrapped with sig_on(), sig_off(). You might
want to run Sage under gdb with 'sage -gdb' to debug this.
Sage will now terminate.

It should be double checked with a vanilla install in case it just reveals
a problem with my libsingular ebuild.
