[MacRuby-devel] mac & ruby question

[Conrad Taylor]

TIm, does gems install correctly with Ruby 1.8.7 which is the default  
in Snow Leopard?  This should be the case.  Next, x86_64 is the  
default under Snow Leopard and your bundles are being correctly.   
Thus, I would recommend sticking with default compilation settings.    
For example, the following is all you need:

gem install hpricot

Thus, I would recommend going through the process again of reinstalling.

Good luck,

-Conrad
