I was getting errors thrown for the libxml-ruby lib when updating my gems, so I decided to install the gem causing the issue, hoping that a fresh install would solve the problems. I am now unable to install it. It seems to have an issue finding some libraries, but I am unsure if they are needed, since I did have it installed before, but if they are where to get them. Thanks for any help. * * * $ sudo gem install libxml-ruby Building native extensions.
