The above message contained the following:

That error should be ignorable.  If you want, you can add a "-f" option
to the command "rm conftest conftest.c", which is near the end of the
"configure" script and then execute the command "make distclean" and
then re-execute the configure script.

I assume you're referring to this:

If the file "udunits/udunits.cc" exists, then the make(1) would try to
use the utility "@CXX@" to link together the udunits(1) program.

Does the file "udunits/udunits.cc" exist?  If so, then remove it and try
again.

What are the contents of the file VERSION in the top-level
source-directory?
