Just want to mention a few things:

- many software are inconsistent where the install man pages -- so they 
need to be patched one way or another. (We patched many from hard-coded 
share/man to just man.)

- for years, autoconf default to just PREFIX/man. But this changed in June 
2006: Since Autoconf 2.60, mandir has a different default value (changed 
from $prefix/man to $datarootdir/man). Of course that is an easy 
workaround, but just shows that a huge amount of software installs are now 
(or will soon be) using PREFIX/share/man.

I was using this for years because my LOCALBASE was /usr. And I didn't 
like /usr/man/. :)
