Thanks, but it's just "Mr".  Please call me Steve.

In order to build the UDUNITS package with a Fortran interface that is
acceptable to the pgf90 compiler, the environment variable CPPFLAGS must
define the C macro "pgiFortran" before the configure script is executed.
Unfortunately, the above settings define the right macro (pgiFortran)
in the wrong environment variable (PPFLAGS) and the wrong macro
(f2cFortran) in the right environment variable (CPPFLAGS).

Please try the following:

    1.  Go to the top-level source directory of the UDUNITS package.

    2.  Perform steps 3 through 5 described near the end of the file

    3.  Ensure that the environment variable CPPFLAGS contains the
        string "-DpgiFortran" (without the quotation marks).  Judging from
        the previous settings, you should probably define it like this:

            setenv CPPFLAGS '-DNDEBUG -DpgiFortran'

        Don't define the macro "f2cFortran" in this variable.

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

Please let me know if this helps.
