Thanks!  I tried doing:

> cd llvm30/build
> ../test-suite-3.0rc4.src/configure
 . . . configure output
> cd ../test-suite-3.0rc4.src
> gmake LLVMCC_OPTION=clang ENABLE_BUILT_CLANG=1

And got the same error as I described previously.  On the assumption that my flailing around had
contaminated my environment, I decided to start from scratch with the test-suite.  So I deleted
the test-suite directory, downloaded it again, unpacked it, and retried this same set of commands.

Again, the configure appears to execute normally.

This time I get a similar, but not identical error:

Makefile.common:13: Makefile.config: No such file or directory
Makefile.common:19: /Makefile.rules: No such file or directory
gmake: *** No rule to make target `/Makefile.rules'.  Stop.

This error appears whether I use the options or not, and whether or not I give it a target, like
"report" or "clean".

Just for grins, I also tried using the LLVMCC_OPTION and ENABLE_BUILT_CLANG options on the
configure step, rather than on the "gmake" step.  The configure didn't seem to mind, but neither
did it do anything different.  The same error appears on any attempt to do a "gmake" or "make".

I have the LLVM 3.0rc4 and the clang from the same kit built and installed in my llvm30 directory, and they
appear to be working normally.  Any idea what I'm doing wrong?  Is there a description of the use
of this configure script available?

If it helps, here's the output of the configure step:

One interesting tidbit:  One of the lines is: "checking clang compiler ...  none", and yet, I can do:
kharris at linux-crzw:~/llvm30/test-suite-3.0rc4.src> clang -v
clang version 3.0 (tags/RELEASE_30/rc4)
Target: x86_64-unknown-linux-gnu
Thread model: posix

Ideas?

Thanks again!
        -Kevin
