Due to limitations with our mail system, would you please send files as

You should use the g77 option "-Wno-globals" to avoid getting messages
like this.

Apparently, the g77 compiler is adding an extra underscore to external
names that contain an embedded underscore.  This can be accomodated by
defining the "f2cFortran" macro when compiling C code.

Try the following:

    1.  Go to the top-level source directory.

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

    3.  Ensure that the environment variable FFLAGS contains the string
        "-Wno-globals" (without the quotation marks).

    4.  Ensure that the environment variable CFLAGS contains the string
        "-Df2cFortran".

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

Please let me know if this helps.
