Martin,
Thanks! That works and builds on OSX, both intel and ppc.
Another problem now is that doctesting this file fails
many times with the new Sage prerelease:
devel/sage-main/sage/rings/polynomial/polynomial_singular_interface.py
The errors all involve killing variables that aren't defined anymore
(which is something singular hates doing).
If you comment out the "kill %s" code in interfaces/singular.py, then
all the errors go away.
I'm not sure if this is a problem with the new version of Singular, or
a change somewhere else in Sage, etc. So, two questions:
(1) Is there a way to do the following in Singular:
if the variable var is defined then
del var
(2) If "no" to 1, could you at least build the prerelease, try doctesting
that file, and see if anything occurs to you?
Thanks for any ideas.
William
