There was some mention in the most resent rubymotion release notes that rubymotion was now capable of writing Mavericks os X Apps (including eval() ). So there is a solution. I am not sure Laurent will be willing to share the solution back to macruby though. Tim On Sat, Nov 2, 2013 at 7:44 PM, <macruby-devel-request@lists.macosforge.org>wrote:

Something seems to be broken since the upgrade to Mavericks. Macgems don?t want to load anymore:

Robs-iMac:~ rob$ macgem list /usr/local/bin/macgem:9:in `<main>': undefined method `summary_indent=' for class `OptionParser' (NameError)

This is just an example. A ?require macgems? followed by e.g. ?require uri? results in similar errors.

Anyone any clue?
