Scripts in that install will get installed. That doesn't mean that
scripts in "build_requires" will get installed if the user has
configured build_requires not to be installed but only made available
during build. That's a perfectly reasonable use case -- one of the
reasons why "build_requires" exists distinct from "requires" in the
first place.

What about ActiveState and the PPM build system? And I would imagine
that some of the unix distributions might similarly need to confirm
that "test" works successfully and then package up blib without
installing. There are lots of 'real users' -- some might well load
the CPAN shell and run 'test Foo::Bar::Baz' before calling 'install
Foo::Bar::Baz'. The distribution shouldn't care. CPAN.pm should make
sure listed dependencies can be found.

I'd suggest searching in $ENV{PATH} and $Config{whateverbin} and
returning an array of paths for any commands that match. (Extra
credit -- match frobnitz/frobnitz.exe/frobnitz.bat on win32). Haven't
really thought about priority. Probably $ENV{PATH} should take
precedence as it's what shows up on the command line.
Figuring out whether any path returned is the 'right' frobnitz is an
exercise for the programmer.
