It appears from the above that the C compiler, /bin/cc, doesn't
understand the options that were used to build the perl(1) utility.

Do you want or need the perl extension module to UDUNITS?  If you don't
need or want it, then the simplest thing to do is to not build it by
setting the enviroment variable PERL to the empty-string prior to
executing the configure script.

If you do want or need the perl module, then you'll have to ensure that
the same compilation environment is used to build the UDUNITS package as
was used to build the perl utility.  You can discover this environment
via the "-V" option to perl.  Use the information to set the environment
variables CC, CPPFLAGS, and CFLAGS prior to executing the configure
script.

Remember to do a "make distclean" before re-executing the configure
script.
