This can't be a good solution. The symbol PyUnicodeUCS4_AsUnicode
indicates your system Python that was compiled with
--enable-unicode=ucs4 (enabling 4-byte Unicode strings). The Python
binary that came with Chimera on my system
was compiled with --enable-unicode=ucs2.
When you compiled matplotlib with your system python, it read the system
python headers and made some references to
the Python 4-byte unicode functions. I'd bet dollars to donuts that if
you attempted to do anythign with Unicode
in matplotlib from that point you'd experience some problems.
Please try downloading the Python headers for Chimera, install those,
and build/install matplotlib using the Chimera python.
