I've updated the Darwin pkgsrc bootstrap kit, found as always at:

ftp://ftp.netbsd.org/pub/NetBSD/misc/agc/darwin-bootstrap.tar.gz

User-visible changes in this update:

* Fixed CXX definition ("c++", not "g++"). This helps a wee bit when
  building software written in C++.

* Provided "ufsdiskimage", a script to assist with creation of
  UFS-format disk images.

* Added a README.

By decree, there are no bugs, but if you encounter any problems, please
send-pr. Conversely, if it works well for you, I'd appreciate hearing
about it.
