You should learn how to redirect both the standard output and standard
error streams to the same output file so that error messages immediately
follow the commands that cause them.  This saves time.

The "make.log" file contained the following:
    c89 -c -O -I../port/misc -I../port/cfortran 
-DUT_DEFAULT_PATH='"/home/imdps/giri/udunits-1.12.2/etc/udunits.dat"' 
-Df2CFortran -DNDEBUG utlib.c
The C macro that should have been defined is "f2cFortran" (with a
lower-case "c") rather than "f2CFortran" (with an upper-case "C").  I'm
afraid that I mistyped the macro in my instructions to you.  Sorry.
Please do what you did before but with the correct macro:
    1.  Go to the top-level source-directory.
    2.  Perform steps 3 through 5 described near the end of
            http://my.unidata.ucar.edu/content/software/udunits/INSTALL.txt
    3.  Ensure that the environment variable CPPFLAGS contains the
        string "-Df2cFortran" (with a lower-case "c").  For example
            export CPPFLAGS='-Df2cFortran -DNDEBUG'
    4.  Perform steps 6 through 9 described near the end of
            http://my.unidata.ucar.edu/content/software/udunits/INSTALL.txt
Please let me know if this helps.
Again, I apologize for my mistake.

Steve Emmerson
