Can't install Nokogiri because of libxml2 dependency

I get this error.

Installing nokogiri 1.6.7.2 with native extensions

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Some experimentation may be necessary for your particular setup but recently I have been able to successfully install the latest nokogiri on OS X 10.11 (El Cap) plus AppStore install Xcode. No homebrew libraries were necessary. Using only the Xcode CLI tools was not sufficient.

Thanks @aramprice. I changed my shell from zsh back to bash and it worked for reasons that aren't immediately obvious to me.

Hi @ClayShentrup ,

Thanks for following up—I'm glad things are working for you. I'd like to keep this issue open as a note to look at running sprout on zsh. As long as bash is available, there's no reason immediately obvious to me why sprout-wrap should not be able to be executed from zsh.

Do you know if anything else in your environment changed from the failed run to the successful run? Did you upgrade any rubies and/or gems?

[ClayShentrup]

@wendorf I'll get back to you on this as soon as possible. Thanks.

@wendorf I've reinstalled oh-my-zsh but the installation still succeeds. I unfortunately don't know what might have changed. Thanks for your concern and I'm sorry I couldn't be more helpful.
