In Pharo the Delay>>wait for one second will not expire anytime soon
in a new image. Use the depedency handling so we can terminate and
restart the loop.
Remove the PackageLoader fileInPackage statement as it is conflicting
with the export as there is no PackageLoader in Pharo. Add a Makefile
to help with invoking the export and create a compat_for_pharo.st for
the methods not provided by Pharo. The testcase is working now.
