It looks like the only definition for the "log10" symbol is the weak one
in the math library.

Try this:

    1.  Go to the top-level source directory.

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

    3.  Ensure that the environment variable LIBS contains the string
        "-lm", e.g.,

            export LIBS=-lm

        or

            setenv LIBS -lm

        depending on your user shell.

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