Hmm...  It could be that gcc should compile the UDUNITS library routines
in your environment with the "-fpic" option.  (We don't have your
environment here, so I can't verify that.  If you still want the perl
extension module for UDUNITS, then try the following:

    1.  Go to the top-level source directory.

    2.  Perform steps 3 through 5 near the end of the INSTALL file as
        before (in particular, use "gcc" for CC).

    3.  Ensure that the environment variable CFLAGS contains the string
        "-fpic", e.g.

            setenv CFLAGS "-fpic"

        or

            export CFLAGS=-fpic

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

The above doesn't set the environment variable PERL to the empty string
like I suggested.  Instead, it sets it to a single space character.
This will cause the UDUNITS build procedure to attempt to build the
perl extension module with a resulting failure (as you saw).  If you
still don't want the perl extension module for UDUNITS, then try the
following:

    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 ''      # NB: no space between the apostrophes

        or

            export PERL=''      # NB: no space between the apostrophes

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

Please let me know if this helps.
