Yeah, but what if someone has it in /usr/local/... or whatever...  I  
guess I could do it with ${x11prefix}, but it would still be nice to  
have a "is this file in any prefix that would be searched for bin:  
lib: dependencies" kind of dependency such that bin:myapp:myapp would  
be equivalent to thisnewone:bin/myapp:myapp
