Coda File System

lwp and includes, and an rpc2/tcpdump question

The sources from don't have rpc2 in them, it seems.
This appears to be the heir-apparent of the 'current' distribution of
tcpdump.  The maintainer ( seems willing to
take patches.

I am trying to build coda for the first time since the lwp split.
I built and installed lwp with --prefix=/usr/local/coda with no
When I ./configure'd coda with the same prefix, it didn't find lwp.
This is really an autoconf issue, but IMHO when a package needs
another package, a user who wants them both in the same oddball prefix
shouldn't need to do special work.  I see that there are
--with-lwp-includes and --with-lwp-dir options, but it would be cool
if the configure script found it in $(prefix)/{include,lib}.

I think this just needs a small change to coda_macros.m4 in
CODA_FIND_LIBWLP, adding $(prefix) to the search path, and adding
modifications to CFLAGS as well.   Well, this patch seems to work for
me.  I think it isn't right; the path found was /usr, but that's
because the -I/-L args are already present in CFLAGS/LDFLAGS, which is
really what has to work out.  Thus, I'm not sure why it didn't work
I'm not 100% certain of this, but I did
do a build after a gmake distclean.

As an aside, I'd vote for removing configure from cvs, and adding a  People already need autoconf/automake installed for
building lwp from cvs, and while automake/libtool might be a bit much,
autoconf is getting to be normal enough these days (IMHO, of course).
