[MacRuby-devel] macirb fails to start on 0.5b2 (undefined method `bind' for IRB::SLex:Class)

[Laurent Sansonetti]

Hi Logan,

Looks like a 32-bit only issue.

$ arch -i386 macirb
/usr/local/bin/macirb:in `<main>': undefined method `bind' for  
IRB::SLex:Class (NoMethodError)

Could you file a ticket on Trac about this? This way we won't forget.

Thanks,
Laurent
