New pynac package available here:

http://sage.math.washington.edu/home/burcin/pynac/pynac-0.1.11.spkg

The package contains fixes for #7822, #6961, #7876, #7363, #6465 and #6559. Apart from this ticket, #7876 contains printing changes. Doctests should be run with the patch from that ticket applied as well.
