man page installation

["Allan P. Magmanlac" <allan_(_dot_)_magmanlac_(_at_)_nrns_(_dot_)_ca>]

Hello,
   Does anyone have an idea how to update a man page relating to a 
particular installation?
For instance, openssl is installed when openbsd system is installed. 
Then I upgraded the openssl version to the latest one. What should be 
done to ensure that when the command
#man openssl
is invoked, the man pages that come with the upgraded openssl will be 
called instead of the
openbsd manual reference manual.
