I suspect that your perl(1) utility was built using a different compiler
than the one you're using to build the UDUNITS package.  In general, if
you want the perl UDUNITS extension module, then the same compiler must
be used to build the module as was used to build the perl utility.

You can discover what compiler was used to build the perl utility via
the following command:

    perl -V

If I'm correct, then you have several options:

    1.  If you don't need the perl extension module, then follow steps 3
        through 9 near the end of the file INSTALL.  At step 5, ensure
        ththat e PERL environment variable is set to the empty string.

    2.  If you want the perl extension module, then you must either

        A.  Build a perl utility using the /opt/SUNWspro/bin/cc 
            compiler.
        
        or

        B.  Build the UDUNITS package using the same compiler that built
            the perl utility.  To do this, perform steps 3 through 9
            near the end of the file INSTALL.  At step 5, ensure that
            the environment variable CC is set to the compiler that
            built the perl utility.

Please let me know if this helps.
