Arrrrggghhh !!  9.2-RELEASE sparc64

configure: error:
The selected GCC C++ compiler is not new enough to build LLVM. Please
upgrade
to GCC 4.7. You may pass --disable-compiler-version-checks to configure
to
bypass these sanity checks.

root at bulldog:~# gcc -v
Using built-in specs.
Target: sparc64-undermydesk-freebsd
Configured with: FreeBSD/sparc64 system compiler
Thread model: posix
gcc version 4.2.1 20070831 patched [FreeBSD]

Guess I'll have to try 10-RC5 (or wait till 10 RELEASE ??)
