Description of problem:

The example in the man page for makewhatis shows that the whatis
database is created local to the directory specified in manpath
as stated here:

To rebuild only /usr/X11R6/man/whatis and /usr/local/man/whatis

              makewhatis /usr/X11R6/man /usr/local/man

In reality, the only whatis database being created or updated by 
the makewhatis program is the one in /var/cache/man/whatis.  
Can this be fixed?
