Thanks, your solution seems reasonable. lib-terminal runs a test behind
our back when we source it, which is a little funny.
Potentially we could turn its test into a lazy prereq, but I think that
does not quite work. In addition to setting the TTY prereq, it defines
the test_terminal function, and lazy prereqs happen in a subshell, IIRC.
One option would be to _always_ define test_terminal. Right now we rely
on it failing to exist to catch tests which should fail to correctly
depend on the TTY prerequisite. But we could just as easily have it
report failure in such a case.
Something like the patch below (looks like we should be using $PERL_PATH
instead of "perl", too).

Yeah, this is because we now try to run the tests by default, and skip
them if webserver setup fails. If you want to know why it's failing on
your machine, try running with "-v -i" to see output, and/or looking in
httpd/error.log in the trash directory.
