I'm on OS X 10.6.6 with Ruby 1.8.7-p174.
After downloading the tar.gz of bowline-desktop, I unpacked it, cd'd into the resulting directory and ran:
This produced the following response:
./Makefile.rb:1: Only supports Ruby 1.9.1 (RuntimeError)
from ruby2make:193:in `load'
Is that intended? It would be nice if this could run on the stock Snow Leopard version of Ruby!
Thanks in advance for your help :)
