Error Installing Jekyll - Native Extension Build

I'm having some trouble installing jekyll. Can't quite figure out how to patch the missing link. I think it's an update to Ruby, but RVM is having trouble installing alternate versions of ruby as well.

Heres the full post:

$ sudo gem install jekyll

ERROR: Error installing jekyll:
ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/fast-stemmer-1.0.1 for inspection.
Results logged to /Library/Ruby/Gems/1.8/gems/fast-stemmer-1.0.1/ext/gem_make.out

Does this mean I need to update the version of ruby I'm using via rvm?


Your problem is that either you system doesn't know where make is located at or you don't have it installed. The easiest way to fix this (and probably other issues you'll run into trying to get a ruby system up and running) is to install xcode.

You can get it at for lion. Or it came on a CD with your computer for earlier versions.

If you're using Lion, please see comments below for a link to how to install developer tools on Lion.
