That's a warning that I believe everybody gets, and it seems to have no
consequences.  Unfortunatly, we haven't yet found the required configure.ac,
sysloc.in, or acinclude.m4 change that will get rid of this warning message.

We'd sure like to know how.

The 5.2.1 tarball and the latest cvs snapshot tarball available at
http://people.debian.org/~rafael/plplot.html were built with a particular
set of autoconf, automake, and libtool versions that work (except for the
above warning message with no known consequences) for us. To take advantage
of this tested set of autotools versions do not execute bootstrap.sh.
Instead, simply use the normal configure; make; make install sequence.  If
you have lots of autotools expertise (or only have access to raw cvs) then
you will want to use bootstrap.sh, but otherwise avoid it if you have access
to a tarball.

I didn't spot anything unusual until:

I wonder if that error might be a result of a libcsa header problem.  You
didn't include the libcsa part of your make output.  Please do so. We would
be particularly interested if there was a compiler warning or error for
libcsa. See yesterday's thread at
http://sourceforge.net/mailarchive/forum.php?thread_id=3438434&forum_id=4474
for a possible fix to the libcsa header problem that occurs on some
platforms.

Your problem might also be due to a nameclash for libcsa.  We have now
addressed that issue in cvs, and you can get access to the latest cvs
snapshot results in tarball form built with tested versions of the autotools
at http://people.debian.org/~rafael/plplot.html.

Please let us know your results for that latest tarball.
