Can't install hpricot gem on Ruby 1.9

[znmeb]

I've just built Ruby 1.9 in a local user account (not root) on a Linux system. I tried to install the hpricot gem, but the C extension didn't compile. I think this is something simple, like a missing path or environment variable.

$ gem install hpricot

Building native extensions. This could take a while... ERROR: Error installing hpricot:

I just spent a while to port Hpricot to ruby 1.9 and finally had success. The gem can be found at

http://weez-int.com/gem/hpricot-0.6.gem

But more important i think is to share information on how to create the gem, here are the:

fixed ext/hpricot_scan/extconf.rb: http://p.ramaze.net/19

fixed Rakefile: http://p.ramaze.net/20

The files are also attached to this ticket.

The most important changes here are patching the C generated by ragel (i have no knowledge of ragel, that should be probably fixed on their side, i guess) and that ruby1.9 has no ::Config module anymore, it's RbConfig?.
