Subject: [PATCH] Make location of man file dynamic for OSX

MANDIR is redefined in the case of an OSX App to be a variable, in a
similar way as DATADIR, so it can be determined at startup, and the App
can be 'portable'. The way to concatenate it with the rest of the file
name hd to be made variable-proof.
