  Nope, I didn't guess right.

  Hmm, your rpath stuff is defined in RPATHFLAG, which is immediately
evaluated because of the := operator, so that presumably strips off the first
$ sign straight away.  Then it gets assigned (deferred, this time) to
MAKETARGET, which gets passed down on the commandline to the submake, where it
gets used in the Make.mk rule, so it'll be expanded again there; since it's
already lost the first $ sign, it only has one, so its use in the
BUILDDIR/TARGETNAME rule will be expanded, and I think at that point it's
replaced with the contents of the make variable ORIGIN, which is empty, before
it even gets passed to the shell.

  I think you need to add another $ sign.  Turn all the "$$ORIGIN" into
"$$$ORIGIN" and see if that helps.


    cheers,
