This is a generic problem with autoconf: It goes looking for X, the
compile doesn't work because of Y, and it reports that X is missing.
Of course, one should always check config.log when something goes
wrong, it contains the details of the compiler failure and the failed
programs. 

Our configure starts off with a compiler sanity check, but apparently
it isn't enough?
