Comment(by malb):
Okay, I managed to build 4.8-alpha2 + this ticket on hawk. Just starting
and stopping Sage gives:
{{{

So it tries to clean up LinBox at the end and that's when things go wrong:
{{{
_fini () from
/export/home/martina/sage-4.8.alpha2/local/lib//liblinboxsage.so.0
}}}
any ideas about why?
