If you have your environment set correctly this is automatic. However,  
from your output it seems you don't so make sure you set something like:

export PATH=/Library/Frameworks/GTK+.framework/Resources/bin:$PATH

Also make sure you're not setting PKG_CONFIG_PATH anywhere (this is  
usually not the case, but it appears you have another pkg-config  
installed) and if you do (and want to use it), you must make sure the  
framework path to .pc is first.

Cheers,
Simon


(BTW: normally you should not need to install RGtk2 from sources since  
it's available on CRAN).
