Ah, you are correct. Sadly it was rejected, so it needs to either be 
cherry-picked or put into a separate repository or something - neither 
of which helps much with providing a binary bottle I guess. It's an 
option, but then "someone else" needs to provide those (github/bintray).

I wrote a lot of different installation instructions, and seem to be 
confusing even myself. :-)

Apparently homebrew-cask just calls "sudo installer -pkg *.pkg -target 
/", which is pretty normal and the same command that we describe - so 
wonder what went wrong. You could check if /usr/local/bin/gpg and 
/opt/gtk/bin/gtk-demo ended up in the usual places, maybe try them 
separately ?

Anyway, this Cask thing seems to rather different from Homebrew - more 
of a fork, really.

The GnuPG and PyGTK packages are separate, but the ZeroInstall package 
is supposed to download them and install them unless you "uncheck" the 
optional dependencies - theory being that you already installed them, 
the last time around. Mostly to cut down on the download size, but also 
for licensing.

But http://macpkg.sourceforge.net is getting a bit old, and I plan on 
retiring it. The universal packages are built for Mac OS X 10.6, and 
needs updating. And then comes GnuPG 2 and GTK+ 3 mudding the waters 
further. Probably easier to just do a packaging for 0install, and ship 
it under the GPL instead ?

I'm thinking that it needs a new build only for 10.9 and later, which 
also enables ditching 32-bit. There's always the option of going back to 
plain old tarballs. Just that there quite a lot of them, for everything ?

We have the "Darwin-x86_64" ones on 
http://0install.net/tools/0install.xml ("generic binaries"), but then 
you need to provide gnupg/gtk+. We tried (and failed) with 
fink/port/brew, and pkg isn't too much fun...
