One obvious possibility to look at would be the current working 
directory.  Xcode sets the cwd when it launches an executable, but 
when you run your tool from the command line, the cwd will be whatever 
it is.  Command line tools should deal with the cwd, whatever it may 
be; applications, on the other hand, should not use it.
