I'm still not sure why defining the environment variable TMPDIR as /tmp caused a problem, but it did. TMPDIR defaults to /tmp anyway, according to ""man ar"" which is why I'm a bit confused why it caused a problem. I can't remember why I had bothered to define TMPDIR in the first place, but there must have been some other build at some other time that needed it to be defined. Thanks for all of your help. I suppose that adding a check to make sure that no one else commits this particular act of stupidity might be a good idea, but it's impossible to guess at all of the potential things that could go wrong.--Rob I can put ""unset TMPDIR"" in the spkg-install file for singular. I'm really glad you tracked this down precisely!

But then I'm being dumb, since that just turns the preparser back on. The preparser in SAGE is activated in misc/interpreter.py in this line: # Rebind this to be the new IPython prefilter: InteractiveShell.prefilter = sage_prefilter If you comment that one line out, then restart SAGE (with sage -br) you'll get a SAGE that has no preparsing at all by default. Yet all the library code should work fine and you have the sage library functions available by default. That sounds reasonable. I undid the preparser.py change and commented out the suggested line in interpreter.py. With a few basic tests everything seems OK. I guess the default int is now a Python int, but that is okay for what I'm working on right now. Thanks for sorting this out."
