Eh? You get exactly the same behaviour under Solaris. man defaults to
looking in <somewhere> (see your documentation for the exact
location). Setting MANPATH overrides this.

Mine (Mandrake 9.0) actually says /usr//etc/man.config. Which by
convention tends to me /etc/man.config (stuff// being interpreted as /)

You're using a different version of Solaris from me then (and I've got
2.5, 7 and 8). I've always known it to work like this.

will do what you want (using <default> if MANPATH isn't set).
So the only problem is how to determine the default. Our Solaris setup
consists of
MANPATH=${MANPATH:-/usr/man}:/usr/local/man
However, the Mandrake 8.2 man comes with the manpath command:
manpath - determine user's search path for man pages
So you can simplify all this to:
MANPATH=`manpath`:/new/dir/goes/here
