i thought (may have bit rot) the sunos (ie: 4.1.2) linker added the
the -L paths to the ELF headers.

anyway, "nor should there be"...i agree it should not alter one's
environment, but why not executable's headers?  according to ld.elf_so(1)

     The linker will search for libraries in three lists of paths:

     1.   A user defined list of paths as specified in LD_LIBRARY_PATH and
          ld.so.conf(5).

          The use of ld.so.conf should be avoided as the setting of a global
          search path can present a security risk.

     2.   A list of paths specified within a shared object using a DT_RPATH
          entry in the dynamic section.  This is defined at shared object link
          time.

     3.   The list of default paths which is set to /usr/lib.

so, even if DT_RPATH is populated by the linker, it can be over-ridden by
the user.

just trying to understand...
