I use a script that I call pkgreq (pkg-required). It is

# cat pkgreq
#! /bin/sh
cd /var/db/pkg
pkg_info -R "$1*" | more

The only thing it shows openssl being used for me is Apache-2.0.49. That 
is a no-brainer since Apache was updated to .49 after I updated 
openssl.

One thing to remember is that if a header file had been changed, which 
wasn't the case here, even dynamic library usage may have required a 
rebuild to be safe. If they had to change the typing of a variable used 
by a module, any program that used that module with the incorrect 
typing could have been passing or receiving bad data. Off by one or 
more errors occur when a structure is modified and using programs 
aren't rebuilt.
