Hi,
while trying to build and test Sage Debian Live 7.3, i notice some issue
with meataxe package. While doctests pass on the VM is was built on
(Pentium3 kvm-emulated), the doctests give a lot of errors when the same
binary is run on another platform (it is the same path, so it is not a
relocation issue).
All errors look like the following:
sage -t --long /opt/sagemath/sage-7.3/src/sage/algebras/group_algebra.py

I do not know whether https://trac.sagemath.org/ticket/20136 will fix
this. For now, i am removing it from the list of optional pkgs to install
on SDL.
Ciao,
