Yup. That's pretty much it. I remember jumping on a Ruby project and having to install 50 (not exaggerating at all) gem dependencies. A handful of them didn't build because of my version of (Ruby|GCC|Rails|OS X|MySQL) and of course nobody else knew how to fix it.

I still love Ruby, but now I use it almost exclusively for sysadmin/build type stuff with Rake.

That's the fault of the project for not specifying a Ruby version. In fact any project that is bringing new people on on a regular basis should have a standard environment setup documentation/wiki.

I admit it's pretty dicey with Windows, but between Linux/OS X things are usually pretty manageable.
