The above message contained the following:

I did find the following in our support-email archive:

    http://www.unidata.ucar.edu/cgi-bin/msgout?/glimpse/udunits/471

It describes a similar problem but for a Red Hat Linux system.
Apparently, I fixed the problem by logging onto the system and manually
modifying the file.  Unfortunately, I don't recall what I did.

I believe, however, that I would have tried the following:

    1.  Change the "include" directives in readgeneral.f, i.e,.

            include '/usr/local/include/udunits.F'

        to a C preprocessor syntax, e.g.,

            #include "/usr/local/include/udunits.F"

        where the hash character (#) is in column 1.

    2.  Change the name of "readgeneral.f" to "readgeneral.F".  This might
        cause the compiler to correctly preprocess the file.

Please let me know if this helps.
