"find / -name 'libXau.so.6'" should do (it exists on GNU/* - no BSD box 
around right now, at least)

I was musing with "man ls" but then I realized I am on a Debian box and 
a lot of little stuff is quite different between BSD and the GNU tools 
(Linux is, after all, only a kernel) so any advice I could have given 
would probably be useless. I suspect you can "ls | grep" your way out of 
this, but can't tell you exactly how.

When it comes to BSD, I am a newbie.
