Ruby 1.9.2-dev, OS X 10.5.8. Built ruby from SVN (with --enable-shared), installed RubyCocoa binary 10.5 pkg from Sourceforge, built samples sucessfully into a folder on the Desktop. Attempt to run any of them, they all fail with messages like the following in the Console:
Sep 23 03:22:08 TKNMac com.apple.launchd ([0x0-0x2d02d].com.apple.rubycocoa.MailDemoSimple): posix_spawnp("/Users/ted/Desktop/RubyCocoaApps/MailDemo.app/Contents/MacOS/MailDemo", ...): Permission denied
Sep 23 03:22:08 TKNMac com.apple.launchd ([0x0-0x2d02d].com.apple.rubycocoa.MailDemoSimple): Exited with exit code: 1
Earlier in the Console, I spot what I think is the problem, but I am without ideas how to fix it:
Sep 23 03:09:14 TKNMac kernel: Finder Unable to clear quarantine `RubyCocoa-1.0.0-OSX10.5universal.pkg': 30
The installer seemed to work succesfully, however, so this may be a red herring--I'm otherwise at a loss as to why the samples are all failing to execute. Group and ownership permissions seem fine.
