I should expand on this:

"make install" uses "libtool install" which relinks the targets using the target install location -L paths.  This is what produces the .libs/libfoobar.so.1.2.3T files.  These T files that are renamed and packaged in DESTDIR, but of course the library depdencies (shown by ldd) are broken until all of the packages in the package-set are installed.

And this all breaks if an old libfoobar.so is already installed, since libtool will pick that up, incorrectly, when linking the T file.
Solution to that is to uninstall the -devel package of the old release.  Which is what we did today for graphviz.

(The -devel package contains libfoobar.so and libfoobar.so.0 softlinks.    The real, old libfoobar.0.1.2.so is OK, apparently because libtool knows that its not the version it wants.)
