New pynac package fixes this:
http://sage.math.washington.edu/home/burcin/pynac/pynac-0.1.8.p0.spkg
It also contains fixes for #6244 and #6211, so doctests should be run with patches from those tickets applied.
Jason, can you review this?

Fine by me, works with new spkg.
Note: See
TracTickets for help on using
tickets.
Here is the fix for pynac:
I'll post an updated spkg later together with a fix for #6244.
