The `-lsun' specification is to resolve xdr(3) references under IRIX 4.*
-- it is apparently unneeded under IRIX 5.* and IRIX 6.*.  I suggest
manually editing the Makefiles to remove this reference.  This is fixed
in the next release.

Be aware that I'm currently working on the port to IRIX 6.0.1.  I would
be interested in anything you discover.
