The above indicates that the build process isn't referencing Solaris' network
support library, which contains the XDR functions.  I suggest the
following:

    1.  Go to the top-level source directory.

    2.  Remove the file `config.cache'.

    3.  Define the variable LD_XDR as `-lnsl'.  You can do this either
        in the environment or in the CUSTOMIZE file.

    4.  Re-execute the configure script.  Trap the output in case
        something goes wrong in order to send it to me.

    5.  Re-execute the command `make all'.  Again, trap the output.

    6.  Re-execute the command `make test'.

Please let me know if the above works.
