lang/ruby: ignore minor system version for archdir, like Apple's Ruby

[kimura wataru]

Hi, I'm a maintainer of lang/ruby.

I'm planning to change the Portfile of lang/ruby to ignore minor 
system version for "archdir", like Apple's Ruby.

Ruby uses "archdir" to define install destination of extension
modules, such as "RMagick.bundle". I think it is not convenient 
to need to re-install ruby libraries (port:rb-*) which includes 
extension module(s) for minor upgrade of MacOS X.

Please tell me your thoughts and issues about this change.

before:
 10.4.11-> i686-darwin8.11.0
 10.5.1 -> i686-darwin9.1.0
 10.5.3 -> i686-darwin9.3.0

after:
 10.4.11-> i686-darwin8.0
 10.5.1 -> i686-darwin9.0
 10.5.3 -> i686-darwin9.0


I tested with the following change and got a good result.
