This is, of course, relatively minor. One alternative is to change the
directory name to exclude the lowest version(s), e.g
2010.1/haskell-platform-2010.1.0.1-i386.dmg, so that when new intermediate
versions are uploaded, the directory name still makes sense and doesn't need

Is it possible to build the installer on a Leopard system/virtual machine
such that it will install on a Snow Leopard system?

Yes, I'm using Leopard. A README file should do the trick.

I'm completely ignorant of how the installer packages work, but is it
possible to have one package refer to another? Thus, one installer could
initiate another. Then, at least there is only one click needed for the

I see you have the source at
http://github.com/gregorycollins/haskell-platform-osx-installer . I can try
to look at it at some point.

That's good. Is it possible to include an uninstaller as well?
