The file "make.log" contained the following:


making `all' in directory /home/ldm/UDUNITS/udunits-1.12.4/src/udunits

This indicates that the gcc(1) compiler needs to be told where to find the stan
dard math functions.

Try the following:

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

    2.  Execute the command "make distclean".

    3.  Set the environment variable LD_MATH to reference the standard-math lib
rary, e.g.,

            export LD_MATH="-lm"

        or

            export LD_MATH=/usr/lib/libm.so

    4.  Proceed with building the package as before starting with execution of
        the "configure" script.
