I recall something in a Debian or Ubuntu bug report about them
changing whether or not they use --rpath based on whether the
destination directory was listed in /etc/ld.so.conf.  It appears that
they are still doing this, and that this could account for the
difference in behavior.  (Seems a bit fragile...)

Tim and Johnathan, can you each perform another experiment for me?
First off do a "make uninstall" to ensure that the install path is
empty.

Then, Tim, please add /usr/local/bin to /etc/ld.so.conf and try

  ./bootstrap
  ./configure
  make
  make check

Johnathan, try the opposite: remove /usr/local/lib from /etc/ld.so.conf
then

  ./bootstrap
  ./configure
  make
  make check


Thanks for your assistance on this.  We may be honing in on the
fundamental libtool change that was made in Debian and/or Ubuntu.
