Building curb under Mac OS X
Had a bit of a problem getting curb to work in OS X, but if you have the curl port installed, its easy:
sudo port install curl
cd src
curl -O http://rubyforge.iasi.roedu.net/files/curb/curb-0.1.0.tar.gz
tar -zxvf curb-0.1.0.tar.gz
cd curb-0.1.0.tar.gz
ruby extconf.rb --with-curl-lib=/opt/local/lib/ --with-curl-include=/opt/local/include/
ruby tests/alltests.rb
sudo make install
