Thank you for the detailed instructions, Jason. The patch works!
The details:
Applied the patch in sage 3.1.2 (from downloaded OSX 10.4/PPC binary).
"sage -b" required 13.5 HOURS on my iMac with a 400 MHz G3 processor...
(William said he wanted to know :-)
The tests I previously reported in this thread now perform as I expect.
My application (calculating a vector electric field from a scalar
potential field) also provides correct results.
I see that the trac ticket is in state "needs review", but I don't
have a login id needed to report this review directly.
In my opinion the ticket could now be advanced to an "approved" state.
Regards,
Jim
