I've just tested to build the example application using makeBaseApp.pl 
without changing any files. This works.

But as soon as I add Asyn and Stream I get the error.

If so, then we need to figure out why it is failing to build your IOC appplication, which it built other programs OK.  Is it just the size of the resulting program or something else?
