Comment(by niles):

 Replying to [comment:44 malb]:
 > Hi, I tried to apply the patch against 4.6.alpha3 and it failed
 (bitrot). I can take a look once that's fixed but I think it would be best
 if Mike would take a look as well.

 I finally got 4.6.alpha3 built, but I didn't have any errors applying the
 patches . . . can you double check that you first applied
 [attachment:trac_1956_multi_power_series_new_4.patch] and then
 [attachment:trac_1956_uni_multi_ps_2.patch]? (I did get errors when
 applying only the second of these)  If there are still errors, could you
 send me a snippet of the failure message?

 Thanks for staying with this!
