Unable to start rdebug

I cannot seem to start rdebug on my machine. Everything else seems to be working okay. I've tried updating my gems without much luck. I've开发者_开发知识库 tried some suggestion of setting the arch flag to x86_64 and update the gems. No luck again. I am on a Mac OSX 10.6.6

/opt/.gem/ruby/1.8/gems/linecache-0.43/lib/../lib/trace_nums.bundle: dlopen(/opt/.gem/ruby/1.8/gems/linecache-0.43/lib/../lib/trace_nums.bundle, 9): no suitable image found.  Did find: (LoadError)

/opt/.gem/ruby/1.8/gems/linecache-0.43/lib/../lib/trace_nums.bundle: no matching architecture in universal wrapper - /opt/.gem/ruby/1.8/gems/linecache-0.43/lib/../lib/trace_nums.bundle
from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:29:in `require'

Any suggestions would be of great help. Thanks

Updating the linecache gem should fix this: sudo gem install linecache

If that doesn't cut it, it might have something to do with your gems coming from /opt/ -- mine was failing on /Library/Ruby/Gems/1.8/gems/linecache-0.43/lib/../lib/trace_nums.bundle (and re-installing linecache fixed it).

Or you could work around it by running rdebug in i386 mode: arch -i386 rdebug ...
