[geos-devel] --ldflags oddness in geos-config

pkgsrc is carrying this patch.  When expanded  in our build, this turns

      echo -L${exec_prefix}/lib -Wl,-R/usr/pkg/lib

It seems clear that the rpath type instructions need to be continued on;
without it the build of the program that depends on geos will be wrong.
(I'm not clear on why the -L argument doesn't get duplicated.)

Plus, it seems all the --libs stanzas have -L${exec_prefix}/lib in them,
even though those are lddfags, not libs.

Does this work for anyone, intalling into a prefix not in the default
link path, and using geos-config to build something against geos to a
third prefix so that there isn't a rpath command for the geos libdir?
