This way means I only have to type the name and version once, I'm a 
great believer in if I can make something automatic then eliminate the 
chance the user (mostly me) can get it wrong the second time.  You 
rejected the $(shell basename .... ) approach which I agree with the 
rejection of using another shell to do something that make is quite 
capable of doing just makes sense.  I guess when I started looking at 
all this I used mpg123 version 16930 as my starting point.  I would 
prefer not to see this changed as long at the packaging convention is 
kept the same.  If the ALSA group ever change there packaging convention 
to not use name+version for the folder then I will change the *_DIR to 
suit.  But while it is the same and can be automatically extracted from 
the package filename I would prefer to use this automated approach.

Hope that makes sense, ultimately since I will not be personally 
committing this to SVN it is up to whoever commits this patch to SVN to 
decide.
