p_group_cohomology optional spkg does not install in sagenb.org

[Jason Grout]

I'm upgrading sagenb.org to sage 4.8 and I get some errors when trying
to install the p_group_cohomology package. If you want this package
installed on sagenb.org, please help fix this problem. The error
message is below.

Thanks,

Jason

Simon's already on the job; he fixed this a day or so ago. See

Great! So do people think I should install this new version on
sagenb.org, or wait for it to be totally reviewed? This is the only
thing holding us back from upgrading sagenb.org to 4.8. I actually
already upgraded all the other *.sagenb.org to 4.8 without this optional
spkg.

Thanks,

Jason

I say install it now.  First, it's an optional spkg, and second, Simon's work is pretty trustworthy, in my experience.

Okay, done. Sagenb.org is now upgraded to 4.8.

Thanks,
