I just tried (on OS X 10.5) an install of hpricot, and was told that  
it couldn’t be compiled because the ruby headers could not be found.  
Curiously, I can install it on my notebook, which is also OS X 10.5.  
Anyone know the cure for this? Should I install the latest version of  
Ruby?

Thanks,  
Ken

You need to install Apple’s Developer Tools (Xcode). Details can be
