[more similar warnings omitted]
The problem is that src/string_primitives.o is being included twice: It
is already included in libparrot.dylib, but it is also being included
explicitly on the link line. That strikes me as quite odd. I suspect the
explicit linking to src/string_primitives.o can be omitted when building
pbc_merge.
The other odd thing about this link line is the trailing -L/sw/lib at
the very very end. That's odd. Usually, the -L flags go *before* the
libraries. It may be that Darwin's linker is insensitive to such details,
but, parrot shouldn't assume that all linkers are similarly insensitive.
