Hello,

I am trying to install Passenger on Mac OS 10.5 but running:  
% sudo gem install passenger  
gives me:

Error installing passenger:  
invalid gem format for /Library/Ruby/Gems/1.8/cache/  
passenger-2.0.6.gem

I don’t remember having problems with other gems. Would anyone know  
what the problem is?

Thanks,  
Elle

I would check your rubygems version and then also ask in the Passenger  
group as well.
