Be aware that the netCDF-Perl package *uses* the netCDF library.
Therefore, you must have a correct netCDF library installed on the
system for which you want netCDF-Perl.

It is my understanding that there is no way to supply a binary Perl
extention module library: each must be built by hand on the system for
which it's intended.

I've successfully built the netCDF-Perl package on the following SGI
systems:

    System              C compiler
    ------              ----------
    IRIX 5.3            /bin/cc
    IRIX 6.2            /bin/cc
    IRIX64 6.2          /bin/cc -32

I appears to me that your perl(1) installation has problems (the C
compiler can't handle one of perl(1)'s header files).  I do know that
it is important to use the same compiler and options to build the
netCDF-Perl package that were used to built the perl(1) package.  Could
you be using a different compiler?

The above looks OK.

Please let me know if this helps.
