问题
I am trying to install mechanize on a Mac OS X Version 10.7.3 with ruby version 1.8.7. The problem is with one of its dependencies nokogiri. I have seen other posts about having xcode installe and I do it is version 4.3.2 . Here is the error I am receiving. Thank you in advance.
sudo gem install mechanize
Building native extensions. This could take a while...
ERROR: Error installing mechanize:
ERROR: Failed to build gem native extension.

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/nokogiri-1.5.2 for inspection.

I needed to simply install the command line tools for xcode and it went smooth. The nokogiri gem has to be compiled.

what about this:
pip install mechanize
or
easy_install mechanize
