Hi Al.

so, i am getting RUNPATH, and it is not used to resolve transitive
loading. hence "plugpath" does not work for me (cannot find the plugin).

"plugpath+" does not require transitive depdendency resolution.

what i do not see is how "-rpath" does not break (=override)
LD_LIBRARY_PATH in your setup. i understand that you are not affected by
the behaviour change above, and it sets RPATH in your gnucap executable.
a set RPATH *always* broke LD_LIBRARY_PATH for me (as documented).
