Indeed.  For reference, what's the best way to do this?
What you want, I think, is to run the testsuite either
with an installed compiler or installed library, but I 
thought the testsuite is set up to only look in the 
current tree for both.

Ouch.  This definitely needs to be investigated post haste.
