I have successfully created my first Darwin/MacPorts Portfile for
Orpie. Orpie is a great little RPN calculator program
for the console. Someone committed my portfile, so you should be able to install orpie now with
port install orpie (after a port sync). It was a really easy program to get to build on Mac OS X
in the first place, and I am quite pleased with how simple it is to create a working portfile.
