If your MANPATH is empty (as I believe we recommend), then man will  
automatically search for things in all the locations specified in PATH  
(that is, for every path in PATH, man will look in ../share/man for  
manpages).

Though it's sounding strange for libexec/gnu to be its own prefix.  
apach2, for example, uses ${prefix}/apache2 as its prefix. Granted  
that violates the mtree, which I originally objected to in this  
thread. :/ Guess I don't really know where it should go.
