I need to compile a testsuite like this:

shell_build_command = &join("configure --with-lib-mpi=", &test_prefix(), "gmake")

But MTT errors out with:

Building Shell
Evaluating: &join("configure --with-lib-mpi=", &test_prefix(), "gmake")
Got name: test_prefix
Got args:
_do: $ret = MTT::Values::Functions::test_prefix()
&test_prefix returning: my_mpi/install/dir
String now: &join("configure --with-lib-mpi=", my_mpi/install/dir, "gmake")
Got name: join

It looks like EvaluateString does not like the slashes,
because something silly like this doesn't give me the syntax
error:

shell_build_command = &join("configure --with-lib-mpi=", &test_np(), "gmake")

Note: Below is a patch to give Build.pm visibility of
test_prefix(), though this will also produce the error:

&join("configure --with-lib-mpi=", &shell("pwd"), "gmake")
