The above error messages indicate a bug in the C development environment 
under AIX 4.3.  There's nothing I can do about it.

Fortunately, the bug doesn't prevent the UDUNITS package from being 
successfully built.

You must be the superuser in order to install the perl extension module
for the UDUNITS package.

If you do not want the perl extension module, then you may have the build
process ignore it by re-executing the configure script after setting the
environment variable PERL to the empty string, e.g.

    $ export PERL=''
    $ ./configure >configure.log 2>&1

Recompile the Fortran program with the '-qextname' option.
