Please see ld(1):

     LD_OPTIONS

         A default set of options to  ld.  LD_OPTIONS  is  inter-
         preted by ld just as though its value had been placed on
         the command line, immediately following the name used to
         invoke ld, as in:

           ld $LD_OPTIONS ... other-arguments …

That means if the environment variable is set it is used directly without knowledge
to the build system. Unless the environment is cleared this is always honoured first.
LDFLAGS is not used at all by the linker, it is interpreted by the build system and
then substituted to the option list of the commandline when the linker is called.

Try ldd -r on libgnustep-base.so.1.24 and see if all libraries are found. If not inspect
with dump -Lv to see the RPATH and make sure all directories with linked libs are in the
RPATH. This is also explained at
  http://wiki.opencsw.org/checkpkg-error-tags#toc54


Best regards
