I had some troubles running the buildbot slave through systemd. You service will be selinux confined and some doctests with external programs fail on Fedora 20.

I made #15828 to track this, though I don't (yet) use systemd so I won't involve myself in actually doing the work ;) http://trac.sagemath.org/ticket/15828 Thanks, Keshav -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

Re: [sage-devel] Re: Issue With Implementation of Gamma Function
a last update: MPFR now uses the Von Staudt=E2=80=93Clausen theorem to comp= ute Bernoulli numbers (thanks to Fredrik Johansson for pointing out this formul= a).
