The above indicates that you perl utility was built using the gcc
compiler; while the UDUNITS package was compiled using the native cc
compiler.  Because perl extension modules rely on dynamic linking of
sharable libraries, a mismatch like this can cause problems.

If you need the perl extension module, then I suggest rebuilding the
UDUNITS package from scratch using the gcc compiler:

    1.  Go to the top-level source directory.

    2.  Perform steps 3 through 5 near the end of the INSTALL file as
        before.

    3.  Set the environment variable CC to "gcc", e.g.

            setenv CC gcc

        or

            export CC=gcc

    4.  Perform steps 6 through 9 near the end of the INSTALL file.

If you don't need the perl extension module, then I suggest rebuilding
the UDUNITS package without that capability:

    1.  Go to the top-level source directory.

    2.  Perform steps 3 through 5 near the end of the INSTALL file as
        before.

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

            setenv PERL ''

        or

            export PERL=

    4.  Perform steps 6 through 9 near the end of the INSTALL file.

Please let me know if this helps.
