But I guess you could start by looking at the output from configure (config.log or similar) to find that error message, and then look at the lines above it to see if any more-specific error is reported. If it says something (other than the compiler itself!) is missing, that might give a pointer on what to google for.
And to check for the compiler itself, I suppose: $ which clang $ which clang++ If they do exist (well, yes, you said they do, but when results are unexplained don't rule things out too quickly) then run ldd on them to see if everything they need is found. ĸen -- Whilst all mushrooms are edible, the trick is to eat only those which will prove to be edible more than once.
