The file "make.log" contained the following:

Apparently, the UDUNITS library needed to be compiled with the
"-fPIC" option in order for the UDUNITS Perl extension module to
be built.

Do you need the UDUNITS Perl extension module?  If not, then do the
following:

1.  Go to the top-level source-directory.

2.  Execute the command "make distclean".

3.  Set any environment variables as before.

4.  Set the environment variable PERL to the empty string.  For
    example:

        export PERL=''

5.  Continue with the build process starting with the execution of
    the "configure" script.

If you do need the PERL extension module, then following the
above steps after replacing step 4 with the following:

4.  Set the environment variable CFLAGS to the string "-fPIC -m64 -O2".
    For example:

        export CFLAGS="-fPIC -m64 -O2"

Please let me know if this helps.

Steve Emmerson
