Nokogiri on a standard installation of Leopard is complain-y about a couple of old libraries:
“HI. You’re using libxml2 version 2.6.16 which is over 4 years old and has plenty of bugs. We suggest that for maximum HTML/XML parsing pleasure, you upgrade your version of libxml2 and re-install nokogiri. If you like using libxml2 version 2.6.16, but don’t like this warning, please define the constant I_KNOW_I_AM_USING_AN_OLD_AND_BUGGY_VERSION_OF_LIBXML2 before requring nokogiri.”
Aaron Kalin figured out how to fix this if you’re installing nokogiri as a system gem, but I want to use Bundler and keep my system gems down to the bare minimum. I figured out how to do this under Bundler 0.8.5.

I’m trying out Ruby Version Manager this week, and my first impression is that this is some cool technology. But I wasn’t able to figure out how to get it to install an older version of REE to get around this bug (the “Marshal.load reentered at marshal_load” issue).
Igor P’s solution is correct (just install REE 1.8.7-2009.10), but it took a little fiddling to figure out how to get RVM to use the older version of REE. Here’s how to do it:
cd ~/.rvm/archives
wget -q http://rubyforge.org/frs/download.php/66162/ruby-enterprise-1.8.7-2009.10.tar.gz
rvm install ree-1.8.7-2009.10

Argh! I spent about 5 hours yesterday troubleshooting a failed Ubuntu Jaunty -> Karmic (9.04->9.10) upgrade. It worked fine until I rebooted and then failed to boot. Here’s how I fixed it.

Once again Ubuntu Linux proves itself to be easy to upgrade. Going from 9.04 to 9.10 (one release newer, since their numbering is bsaed on dates) was easy, but included the standard sprinkling of manual re-customization that I’ve come to expect from Debian based systems.

Rails provides some flexible and fairly short controller methods for responding with an HTTP error code. Given that controllers are complicated enough by nature, I’m always looking for ways to DRY them up and make the code easy to understand. So here are some controller methods that make it really easy to provide correct HTTP error responses to clients.
