I'm running into problems when I attempt to build 
cross/m68k-netbsdelf on my OS X box.  Binutils is not being patched 
and I assume that it's due to the differences between OS X and 
NetBSD.  These are the errors I encounter:

===> Applying Darwin patches for cross-binutils-2.9.1.2
1 out of 1 hunk FAILED -- saving rejects to file ./ld/configure.tgt.rej
Patch /usr/pkgsrc/cross/binutils/patches/patch-msixtyeightk failed

==> Applying Darwin patches for cross-binutils-2.9.1.2
Reversed (or previously applied) patch detected!  Skipping patch.
2 out of 2 hunks ignored -- saving rejects to file ./bfd/elf64-alpha.c.rej
Patch /usr/pkgsrc/cross/binutils/patches/patch-aa failed

The rejects aren't being saved too.  I would try to solve this 
mystery but I'm not up to the level of understanding this yet.
