We get this request from time to time; in concept it isn't a huge deal  
(and would allow us to support /usr/local/lib/cups/filter, etc.), but  
if we implement this for all of the helper apps (backends, port  
monitors, notifiers, etc.) the changes get a lot larger.  Then there  
is the issue of precedence - if you have pstoraster in both /usr/lib/ 
cups/filter and /usr/lib64/cups/filter, which one should we run?

If you can come up with a proposal that clearly addresses those issues  
(or just have strong feelings that we should try to do something about  
it instead of getting the Linux distributors to agree on a single  
directory), feel free to file it on the bug page:

     http://www.cups.org/str.php

Probably the simplest fix would be to have the Linux distros provide a  
symlink from /usr/lib64/cups to /usr/lib/cups so that third-party (or  
distro-provided) packages install everything in one place.
