I rarely read directions. I once assembled a piece of furniture for a girlfriend, only to wind up with 10 spare parts. The cabinet subsequently collapsed (as did the relationship, soon thereafter).
While compiling the Ethereal packet sniffer for OS X, I missed some of Jamie Methnen’s directions, and I paid for it with roughly two wasted hours.
Thanks go out to Jamie for finally setting me straight. And..thanks to Martin Fuhrer for creating XDroplets, which made launching my newly compiled X11-based app that much easier.
