Easy Question

[beno <zope@xxxxxxx>]

Hi;
I'm trying to configure a number of programs to work together, including 
openssl and squid. I'm using a makeshift how-to here:

One line says I need to "change path to openssl include files", 
presumably for squid. What does this mean and how do I do it?
TIA,
beno
