 I agree with Lee on this; we must be able to assume some things. So what if
the "fresh Solaris" doesn't have [our test script language of choice]
installed, they just won't be able to run the test suite.

 The test suite needs to use one of the languages mentioned and we cannot
have that language as part of the source tree.

Yes, but autoconf (or at least configure scripts) is meant to run for the
program in question to compile/build/install. In my eyes that is a somewhat
more important issue for most tarball downloaders than running the test suite
is.

... and what if [Perl/Python/Tcl/sh] or a combination of them aren't present
in your build system? We can hardly fail miserably since we can compile,
build and run fine without them (not without sh though).

I'd say we're fine to output a nice message saying "you need at least version
X of language Y to run the test suite" instead. We could have a warning
displayed in the configure script.
