-R or -Wl,-R won't change any link-time thing. those paths are placed
into the RPATH embedded into the binary. sunos4 ld -R also put the
path into the library search path, but this was changed in sunos5 and
in the binutils ELF.
only -L changes the link-time search path (sans some other exotic
options that are more about using a cross compiler.)
i'm not sure exactly understand the question though. are there two
shlibs being linked? or just two with the same name in different
subdirs of the link path?
