Replacing the code in place to find where to put the man pages with
the above code is a bad idea.  Adding the above code, on the other
hand, may actually work, but we should still default to
/usr/local/share/man/whatever (actually, to make it best, try
$PREFIX/man, then try $PREFIX/share/man, then try
/usr/local/share/man, then finally try /usr/local/man)

As an aside, the only platforms I currently support MaraDNS running on
is CentOS 5 and Microsoft Windows.  The reason for this is because
paths to place files, which quite frankly don't matter except that all
the *NIXes should agree on them, are different between Linux and BSD
for no particular good reason.

The best way to get MaraDNS available for your favorite
not-LSB-compliant *NIX is to make a package for your particular
distribution.  This, of course, has the disadvantage that it requires
commitment--said package really needs to be updated whenever I update
MaraDNS (which isn't that frequent since MaraDNS is currently frozen)
with bug fixes.
