You don't have to do it.  Since 1.6, ruby.exe sets $LOAD_PATH
according to its own path.

e.g.,

  $(TOPDIR)/lib/ruby/site_ruby/$(VERSION)
  $(TOPDIR)/lib/ruby/site_ruby/$(VERSION)/$(SITE_ARCH)
  $(TOPDIR)/lib/ruby/site_ruby/
  $(TOPDIR)/lib/ruby/$(VERSION)
  $(TOPDIR)/lib/ruby/$(VERSION)/$(ARCH)
  .

where VERSION is 1.6 or 1.8, ARCH is same to RUBY_PLATFORM,
SITE_ARCH is i386-msvcrt for 1.8 on mswin32 and mingw32, or
same to ARCH otherwise.  TOPDIR is the ruby.exe's directory
with the last "/bin" removed.
