Upgrade Question

[Nathan Brazil]

Hi.  After I upgraded to MacPorts 1.4, I noticed that freetype is now  
at 2.3.2, where the version I have installed is 2.1.10.

I would like to upgrade to the latest version, but  I also have  
several ports installed that depend on freetype.  How do I know if  
2.3.2 is binary compatible with 2.1.10, and if not, is there a  
command to re-compile all the ports that depend on freetype?
