I can't get this to fail for me on Darwin 6.8, but perhaps something
changed/got broken in 7.0. does passing -L or -Wl,-L to either cc or
ld really not work?

I tried setting _OPSYS_RPATH_NAME=-R and the rpath arguments were
stripped from the cc command-line. you should be able to just change
this single line in defs.Darwin.mk to test it.
this is not ideal, since -R will sometimes be present in LDFLAGS and
therefore a manual pkg build in the WRKDIR won't work...

please let me know whether any combination of -L and -Wl,-L arguments
to cc/ld work so I know how to address this.
