A sage with the ecl library interface is available in "/scratch/nbruin/

William,
Thanks for clarifying some of the details of pexpect. I do really want to
understand this because I am starting to use the notebook more and currently
IPython's parallel stuff works fine (there are a few things that need to be
fixed on our side to make it easier though).

OK, here's a little experiment. I thought adding 2 and 2 would be too
hard for now, so I stuck with 1+2. Good news is that

ln(x) is what's used in engineering. I dislike the use of log(x) for
ln(x)
but I'm guessing I don't have much of a choice. All use of log I learn

I think that's maybe a reminiscence from the age of pocket calculators

Hi,
One nuisance in mathematics is the "ln(x)" notation for natural
logarithms by students up to a certain age, followed by the "log(x)"
notation used for exactly the same thing after a certain age. So
I've always taken great pride that in Sage (and most other math
software), "log" is the right
The following problem came up while trying to use ecl as a library
inside sage:
Both sage and ecl use GMP for their multi-precision arithmetic, and
both call mp_set_memory_functions to register their memory managers.
This obviously doesn't work, since GMP only keeps track of one set of

I think as a first step I'll only implement the additional argument
for the two methods "is_field" and "is_integral_domain".

After building sage 4.1.1 on Solaris, I get the above error message if I
run 'make test'. I've not seen this error on previous releases. I have
changed maxima and ecl, but I somewhat doubt they are the cause of the
problem.
Has anything else changed in Sage recently that might have caused this
