Hi Tobias,

The reason this issue has come up is because I'm sitting with Dale
attempting to fix builderCI to work with Squeak 5 so we can follow Dale's
desired 'fixing metacello for Squeak 5' path and have travis test it.  See
here for the travisci result from the work to get builderci running with
Squeak 5 thus far:


Let me know when you're back from vacation and we can look at this in more
depth.   Hope you have a relaxing time.
