I'm probably in the minority on this, but I think tachyon being totally broken in sage-4.1 is bad enough that a sage-4.1.0.1 should be released as soon as possible with this fixed, not waiting for the 4.1.1 cycle to finish in two weeks.
At the very least, perhaps sagenb can be patched. -Marshall On Jul 16, 12:27 pm, Marshall Hampton <hampto...@gmail.com> wrote: > I have added a patch that fixes this, available at: > > http://trac.sagemath.org/sage_trac/raw-attachment/ticket/6542/trac_65... > > Since tachyon is currently broken on all systems in sage-4.1, I fixed > the immediate problem rather than taking the time to improve the > testing of tachyon.py.
