[netCDF #IIA-403412]: NetCDF-4.0.1 shared library compiler options

Hi Sriki,

As far as I know, it should work to just specify CC=gcc and use the 
"--enable-shared" option
to the configure script when you build netCDF.  If your installed version of 
gcc is much
different from the version of gcc used to build perl, there may be a problem, 
but otherwise
it should work.

If it doesn't, an alternative would be rebuilding perl with the same version of 
pgcc you used
for the netcdf library.  The Portland Group has recently made available new 
information about
building various versions of netCDF with various versions of the PGI compilers 
on various
platforms:

  http://www.pgroup.com/resources/tips.htm#NETCDF

but I don't see any similar information for building perl ...
