[cairo] Compile error with Cairo 1.0.0/1.0.2 on Mac OS X

[Bogdan Nicula]

Hi.

Mac OS X has an older version of fontconfig (which is also crash prone). If 
you compiled your own, as it seems, please make sure the linker is using it 
instead of the system one. In general you'll get better results by compiling 
the full stack (freetype, fontconfig, libXft, maybe also libXrender), 
instead of using the rather obsolete system provided ones. To make sure 
'pkg_config' finds the right ones, please set PKG_CONFIG_PATH. You may need 
something like 
PKG_CONFIG_PATH=$YOUR_INSTALLATION/lib/pkgconfig:/usr/lib/pkgconfig.
With the right set of environment variables (e.g. C_INCLUDE_PATH, 
LIBRARY_PATH, ACLOCAL_FLAGS) you should be able to bypass all the system 
provided libraries.
Also, if you generate dynamic libraries, check with 'otool -L' if they link 
to the versions you want.

Cheers,
Bogdan
