Good!

We should support it for now, and thanks very much for testing that support
(which I cannot do on my Debian system which is fully converted to python 2).

Before, I found python2 was not reliable in RH7.2 so I used python1.5 in
that case. If you look at plplot/rpm/plplot_redhat7.2.spec, you will see I
did the following there:

PY_VERSION=`python -c 'import sys ; print sys.version[0:3]'`
export PYTHON_INC_DIR=/usr/include/python${PY_VERSION}/
echo PYTHON_INC_DIR=${PYTHON_INC_DIR}
export PYTHON_MOD_DIR=/usr/lib/python${PY_VERSION}/
export PYTHON_CFG_DIR=${PYTHON_MOD_DIR}/config
export PYTHON_NUM_DIR=${PYTHON_INC_DIR}/Numeric/
export PYTHON_MACH_DIR=${PYTHON_MOD_DIR}/site-packages
export PYTHON_DIR=${PYTHON_MACH_DIR}
./configure ...

I would stick with python-1.5 until RedHat are confident enough of python-2
to call the associated command "python" rather than "python2".

To solve the above and other split problems, I have just committed
a revised setup.py.in to cvs which replaces the python 2.x method, e.g.,

incs_list = incs.split(" ")

with the python 1.5 (and python 2.x) string function

incs_list = string.split(incs," ")

Please give that a try, and I hope that weeds out all python-2 only constructs
that have crept in since plplot-5.1.0.
