Thank you, Dieter, for the update.
Since I posted my results on the subject of upgrading maxima to the
latest release in the PCLinuxOS forum I have received no comments on the
post, so maybe there isn't much interest. I, however, am interested in
keeping my personal copy of maxima as current as possible because I rely
on its accuracy for mathematics calculations I need to do from time to
time. I'm not working on anything earth-shattering, but it's important
to me.
I really do appreciate all of the assistance I've received from all the
people who've responded to my requests for help with maxima-related
questions.
Sincerely,
Paul Bowyer
