  • Ruby Troubleshooting: Hpricot On OS X Leopard

    If you upgraded to Leopard, you may be getting this nasty error when trying to install Hpricot, which is required by other popular gems such as mechanize..

    The issue is that Xcode 3 must be upgraded as well; Hpricot’s native components cannot be built with the older Tiger development tools on Leopard. After installing Xcode 3 from either your Leopard DVD or Apple Developer Connection, run the install again…
