Ruby - Can't Install Curb

Hi fellas!

When trying to install Curb(0.7.15) with native extensions I got this message:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
        /home/daniel/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb

Gem files will remain installed in /home/daniel/.rvm/gems/ruby-1.9.3-p194/gems/curb-0.7.15 for inspection.

An error occurred while installing curb (0.7.15), and Bundler cannot continue.
Make sure that `gem install curb -v '0.7.15'` succeeds before bundling.

As suggested, I tried to install curb but no success!

The solution?

Install this: libcurl4-gnutls-dev and guess what, problem SOLVED!

On Fedora you do:

$ yum install libcurl -devel.(64 or 32 bit version)

Adios!
