/usr/local/man vs /usr/local/share/<portname>/man and manpath

[Anton Shterenlikht]

Some ports install man pages under
	/usr/local/man
e.g. graphics/xfig,
while other ports do it under
	/usr/local/share/<portname>/man
e.g. graphics/xpdf.

>From what I understood from manpath(1),
it is hard to specify the path to the second
type of man pages, because each new
port name needs to be specified separately.

Currently my manpath returns:

/usr/share/man:/usr/local/man:/usr/share/openssl/man:/usr/local/lib/perl5/5.16/man:/usr/local/lib/perl5/5.16/perl/man

Is this a problem to be solved by the
user's environment?
If so, what is the recommended way to solve it?

Or is this a problem with some ports
creating man pages in the wrong place?

Thanks

Anton
