swig -version

How do I check my version of swig? I'm not sure.

    It looks like swig is throwing an assert when it tries to convert
    storage.i.  I can't imagine this has anything to do with your
    installing numpy.   What version of swig are you using?


        A more complete error message is below:

           I tried to do this and re-build NOX.
           The commands I used to install numpy was:

           sudo apt-get install python-numpy

           The error in NOX was:

           swig: Modules/lang.css:330: Language::Language(): Assertion
           '!this_' failed.

           Do you know what this means?

           Thanks,

               Yeah, we've run into this problem before.  I believe the
               segfault is in numpy and we got around it by compiling
        against
               a more recent version of numpy.

                   Hey,

                   I put this line of code

                   import matplotlib

                   into my NOX module (Python graphing utility).
                   Now, when I start NOX, it exits on a segmentation
        fault.

                   Does anyone know why this is happening?

                   Thanks,

                   Albert
