      It seems your solution is very broken. It assumes python library is

      You should never check for a library as a file.

      Your check will probably also break libtool plugin support (when it will

  Not sure what the ideal solution is.  I notice taht on redhat systems, the 
python library is in /usr/lib/python../config (eg, the 'nonstandard location 
check'), and that check only looks for static libs also.

  Ideally, I'd like to use the AC_CHECK_LIB function.  Unfortunately, after the 
first check for python, configure caches the result, so even if you pass 
different search options for the library check, it won't work.

  I'm not sure the correct approach.  I note that this check is still in place:

  AC_CHECK_LIB($python, PyArg_ParseTuple,[PYTHON_LIB="-l$python"])

  where python will be derived from the locatin of the include file.  However, 
if the include file is in a standard place (/usr/include/), this won't work.

  I'm not sure the right approach - I can certainly put the old check in, but it 
still leaves it only searching for static libs.

  The problem with this check:

                         PYTHON_LIB=`echo /usr/lib/python*/config/libpython*.a`

  Is that if you have multiple instances, it finds them all, which probably 
isn't what you want.
