Sage 3.0.4 Fails with "ImportError"

[Roberto Dominijanni]

Sage 3.0.4 compiled successfully on a system with two 3 Gb Xeon
processors running the AMD64 flavor of ubuntu-8.04. Invoking sage from
the command prompt gives the following:

Any ideas on how I can go about fixing this?

The Pyprocessing module was not installed/compiled properly. This
indicates that the build did not finish and/or something bad happened.
Please upload install.log to some place and post a link so I can take
a closer look.

Hi Robert,

I looked at your build log you send me off list and lcalc failed to
build. I suspect it is due to some CFLAG option we set, namely using "-
static-libgcc". According to the log this was added a while back, but
I see no reason to add it at all. Can you take the spkg at

http://sage.math.washington.edu/home/mabshoff/lcalc-20080205.p2.spkg

and put it into $SAGE_ROOT/spkg/standard and run "make" again from
$SAGE_ROOT since you did not finish building Sage. Let me know how it
goes.

Cheers,

Michael

Michael,

That did the trick. Sage finished compiling and passed all its tests.
Thank you very much.
