I have ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0]
installed in my Snow Leopard Preview Release. Rails runs OK, but I can’t
install some gems with native extensions. The following error appear:
$ sudo gem install bluecloth

The same error happens with many gems. I tried already update rubygem
(the installed version is 1.3.4), but the problem persist. Any ideas?
I decided to install another version of ruby at /usr/local/ruby-1.8.6
and point executables (erb, gem, ruby, etc.) to the new ruby dir. All
went right, and ruby (1.8.6) and gem are working. But when I try to
install any gem, I get:

You also have the dev tools installed?
Thank you for the response. Yes, I had… but since I didn’t find a
solution, I reinstalled Leopard. It is better wait for the final release
of Snow Leopard

Hi I’m having the same problem, latest copy of xcode, dev tools and snow
leopard but I cant get some of the gems to build. It seems like gem
can’t find the header files for Ruby…Any ideas?

Well, you can install other Ruby. I followed this tutorial and it worked
great:
(the installed version is 1.3.4), but the problem persist. Any

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
If this file really doesn’t exist you should submit a bug report to
Apple.
I just had to do the same thing for a new MacBook Pro purchased
just a couple weeks ago. Good news is, this still works. Bad news is,
it’s takes 9GB if you go whole hog and install xcode+iOS tools.

I’m running 10.7.3 on a MacBook Air (11-inch Mid 2011 i5 CPU)
I have installed XCode v4.3 (latest) from the App Store (This computer
has no DVD drive)
I know that the ruby.h file does exist because I find it with the locate
command. It exists several places, like this:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/Headers/ruby.h
Perhaps my gcc environment variables need to be updated?

Any advice is greatly appreciated.

I had this particular problem as well and here’s how I got around it:
For OS 10.7 + XCode4.3 only open Xcode preferences, select the
“Downloads” button, select the “Components” tab of Downloads, highlight
“Command Line Tools” and press the install button. Gem install rails
didn’t give me any trouble after that. Hope that works for you too,
