request.pathdelim = "/";
which should obviously be a backslash for Windows. I then modified
files that used the backslash and replaced them with request.pathdelim.
For instance Log.cfc has this updated line near the top:
variables.instance.logFile = request.config.getValue("logfolder") &
request.pathdelim & "cfpaypal.txt";
It also affected Config.cfc--not sure if there were other files.
Anyway, these changes allowed me to run the scripts on linux.
