Build error on Solaris 10 (SPARC) if Python 2.6.5 is in /usr/local

[Dr. David Kirkby]

I just installed Python 2.6.5 on one of my SPARCs, and now find that the python
in Sage is interacting with the one in /usr/local in an undesirable way. It
generates a *HUGH* number of error messages in the log - the log file is now 267
MB, compared to the usual 30 MB or so. Hence the error messages make up over 200 MB!

sage: An error occurred while installing matplotlib-0.99.1.p4

I don't know if there is anything I can do to mathplotlib to tell it to only
look at the python in $SAGE_ROOT/local, and not in /usr/local.
