Finding the python version should be straightforward. The last stanza
of cmake/modules/plplot.cmake provides a template for running python
to generate useful information about python.
Modify that template to run, e.g.,
python -c "import sys; print sys.version.split()[0]"
to obtain the version. I suggest the result should be stored unmodified
(see below) in the PYTHON_VERSION variable.
Note, however, that the version generated this way may have some
trailing non-numeric data you will need to filter out with the cmake
string command before you can make numerical comparisons between say
2.6.0 (when the necessary buffer functionality is first available to
python) and ${PYTHON_VERSION}. For my (Debian squeeze) system I
obtain, for example, "2.6.5+" from the above command.
