Fatal Error with Ruby/GTK2, Homebrew, Green Shoes, and OSX Snow Leopard

I posted the below question to the Shoes mailing list and got back the
following responses:

"Could you post your problem into ruby-list ML?
I think we need Ruby/GTK2 developer's help."

I am now posting the issue here to see if Ruby/GTK2 developers can help?
Thanks

-------START OF ORIGINAL EMAIL------------------

I am trying to get green shoes to work on Snow Leopard. I used homebrew to
install gtk+ and rvm to install ruby 1.9.2-p180. I believe that I installed
cairo v1.10.0 correctly, but when I try gtk2 0.90.5 I get the error messages
below. I have tried all I know. Any advice?

It means rcairo can't find cairo.h. Could you check

I can't find that directory at all. is it ~/opt/local/......? much less the
file

How did you install cairo 1.10.0?
rcairo needs to find cairo.pc for detecting include path of
cairo. cairo.pc has the information.

Here are the instructions that I followed (from green shoes github site):
Via Homebrew

(untested, but probably the recommended approach for Intel Macs)

This approach would be basically as per the Macports instructions, but using
the equivalent Homebrew <http://mxcl.github.com/homebrew/&gt; commands to
install Ruby 1.9 and GTK2. So, something like:

   1. Install Homebrew <http://wiki.github.com/mxcl/homebrew/installation&gt;
   2. Install Ruby 1.9 brew install ruby (Alternatively, you may want to
   use RVM <http://rvm.beginrescueend.com/&gt; to install Ruby1.9)
   3. Install GTK2 brew install gtk+ (This should pull in all other
   dependencies such as Cairo)
   4. You may then have to update the Rubygems version if it isn't greater
   than 1.3.7 (updating shouldn't do any harm anyway): sudo gem update
   --system
   5. Install Ruby bindings: sudo gem install cairo -v=1.10.0 and sudo gem
   install gtk2 -v=0.90.5
   6. Install the Green Shoes gem: sudo gem install green_shoes

I belive gtk+ is supposed to install cairo. I tried step 5 again tonight and
now I get errors.

kou,

I tried port install cairo and opt/local/include was created but no cairo.h

If you installed Ruby with rvm, then everything is done locally, so you
should not need "sudo" for installing the gems. I am pretty sure that using
sudo with rvm can cause issues.

I think macports requires sudo "sudo port install" because of where it
installs to.

I am also pretty sure that if you use both macports and homebrew, then this
can cause you issues. The homebrew page should have more information about
its compatibility with macports. At the very least, you'll probably have to
uninstall the cairo that you installed with macports.

If you installed Ruby with rvm, then everything is done locally, so you

Yep, because sudo switches users, and so that changes your environment,
which is the whole thing that rvm is based on. rvmsudo lets you elevate your
privledges while not screwing everything up.

can cause you issues. The homebrew page should have more information about

Yep, they dont' play nice:

Issue Resolved.

It was apparent macports and hombrew were conflicting. I deleted macports
and homebrew and reinstalled homebrew and followed the instructions on the
green shoes github page. Using RVM and Ruby 1.9.2, everything worked
perfectly. I'm not sure but I think macports could have been affecting RVM
b/c I had had several issue (even prior to this) using gem install on RVM.

Lesson: choose Homebrew or Macports, but not both.

Thanks for the advice.
