Today I’ve upgraded my gems and noticed that when running my autospec I get an odd error:

[01:09:25 /usr/local/lib/ruby/gems/1.8/gems/ruby-ole-1.2.10/lib/ole/storage/base.rb:146:load]

WARN   root name was “R”

And my autospec would keep printing out:
sh: line 1:  6303 Trace/BPT trap          /usr/local/lib/ruby/gems/1.8/gems/autotest-fsevent-0.1.2/fsevent/darwin/fsevent_sleep ‘/Users/andrew/rails_apps/example_com’ 2>&1
sh: line 1:  6307 Trace/BPT trap          /usr/local/lib/ruby/gems/1.8/gems/autotest-fsevent-0.1.2/fsevent/darwin/fsevent_sleep ‘/Users/andrew/rails_apps/example_com’ 2>&1
Unfortunately I don’t have the time to look into the fsevent code to see if I can make a work around, however I found that you can remove the gem (‘sudo gem uninstall autotest-fsevent‘) and install the older version (‘sudo gem install autotest-fsevent --version 0.1.1‘)
Hopefully this helps someone out!
UPDATE: I forgot to mention I was using a Mac OS X 10.5.8, and based on the History.txt they made changes effecting Macs.
UPDATE 2 (Oct 22, 09): It seems that the same issue exists in fsevent 0.1.3 as well
UPDATE 3 (Mar 05, 2010): Issue still present in 0.2.1 however I found out that the error is only for OS X 10.5 and will not happen on OS X 10.6.
The full error message is:

/usr/local/lib/ruby/gems/1.8/gems/autotest-fsevent-0.2.1/fsevent/darwin/fsevent_sleep ; exit;
~%  /usr/local/lib/ruby/gems/1.8/gems/autotest-fsevent-0.2.1/fsevent/darwin/fsevent_sleep ; exit;
dyld: unknown required load command 0x80000022
zsh: trace trap

The only work around (outside of downgrading to version 0.1.1) is to copy fsevent_sleep from version 0.1.1 to version 0.2.1. However I’m not sure how stable that solution is.
