Yes.

%runtest --version
WARNING: Couldn't find the global config file.
Expect version is       5.42.1
Tcl version is          8.4
Framework version is    1.4.4

I dunno dude. This is pretty much a deal breaker for me: I've got to be
able to do something like this, preferably by editing testsuite_files directly.
