balt has asked for the wisdom of the Perl Monks concerning the following question:

Hi all,

I'm at an impasse trying to install the Gtk2 package on my OS X machine. sudo cpan, then: intsall Gtk2 results in:

---- Unsatisfied dependencies detected during ----
----          XAOC/Gtk2-1.242.tar.gz          ----
    Pango [build_requires]
    Glib [build_requires]
    Cairo [build_requires]

[download]
When I try to install any of the above dependencies, the install fails with this same message (substitute the package name): 
  CPAN.pm: Building X/XA/XAOC/Cairo-1.090.tar.gz

Package cairo was not found in the pkg-config search path.
Perhaps you should add the directory containing `cairo.pc'
to the PKG_CONFIG_PATH environment variable
No package 'cairo' found
 at Makefile.PL line 58
*** can not find package cairo >= 1.0.0
*** check that it is properly installed and available in PKG_CONFIG_PA
+TH
 at Makefile.PL line 58

[download]
and it's all an evil downhill spiral from here. Any ideas? Cheers - Balt

    On macosx, my usual approach with opensource projects is (in this order):
    1. Use binary distribution or installation procedure from the project site. For your problem: Re: Gtk2 installation on OS X fails
    2. If there is nothing for macosx on the project site, I use the Macports package http://www.macports.org/install.php (check the freshness of the package)
    3. Finally, I try to compile (or use cpan...) myself and I fail :-)
