Hi Richard, thanks for the report.  I've committed a workaround to
scipy r4767 in SVN so this issue doesn't appear in the coming SciPy
0.7 release.  I'd ask you to try using this version to see if the bug
is indeed fixed.  If you'd like to apply the same workaround to 0.6
you can use the following script:

sparse/linalg/dsolve/SuperLU/SRC$ for f in *; do sed
's/c_abs/slu_c_abs/g' < $f > temp; mv temp $f; done;

It simply renames c_abs() and c_abs1() to slu_c_abs() and slu_c_abs1()
respectively.

We really need to update our SuperLU code to a more recent release.
