I found different ways to detect if frotz is installed in the test suite:
a) use "type"    (Should be the fastest ?)
b) call the command directly, check the exit code
c) "! test_have_prereq" (easy to understand, propably most expensive ?)

Do we really need  "which" to detect if frotz is installed?
