[MacRuby-devel] Fwd: How do I get gems into XCode/MacRuby environment?

[Paul Davis]

Ah. Thanks Morgan. That indeed has things working. I had thought MacRuby was running on 1.9.x - probably because the first line on http://www.macruby.org is "MacRuby is an implementation of Ruby 1.9 directly on top of Mac OS X core technologies...".

In fact, when I run "puts system('ruby -v')" from inside a MacRuby/XCode process I get:
	"ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]"

Setting the GEM_HOME and GEM_PATH in the Scheme to point to my 1.8.7 gems has them loading and running.

Still haven't tested deploy.

PD
