The above look OK.

It appears from the above that attempting to use the UDUNITS perl
extension module results in an unresolved reference for the symbol
"__mth_i_dpowd".  I've never seen this symbol before, so I don't know
what is referencing it.

Here are some possibilities:

    1.  Do you need the perl extension module?  If not, then you can
        skip building and installing it and your UDUNITS library should
        work just fine.  To skip the perl extension module do the
        following:

            1.  Go to the top-level source directory.

            2.  Execute the command "make distclean".

            3.  Set your environment variables as before.  Remember to
                have CPPFLAGS contain the string "-Df2cFortran".

            4.  Set the environment variable PERL to the empty string,
                e.g.

                    % setenv PERL ''

                or

                    $ export PERL=''

            5.  Execute the configure script.  Redirect as before.

            6.  Execute the command "make".  Redirect as before.

            7.  Execute the command "make test".  Redirect as before.

            8.  Execute the command "make install".  Redirect as before.

            9.  Execute the command "make clean".

    2.  If you need the UDUNITS perl extension module, then is the
        compiler that you're using (pgcc) the same one that was used to
        build the perl utility?  If not, then you have to ensure that
        you use the same compiler.

    3.  There might be a library somewhere that contains a definition
        for the unresolved symbol (__mth_i_dpowd).  Try using the
        "nm" utility to find it.  When you've found it, add a
        reference to that library to the LIBS variable in the makefile
        "perl/Makefile.PL".  Then go to the top-level source directory
        and execute the following commands:

            make perl/clean
            make perl/all
            make perl/test

Please let me know which possibility you wish to persue.
