VirtualBox-OSE 4.2.22 fails to configure (g++ not found)

[Kevin Oberman]

I attempted to upgrade to 4.2.22 today on my RC5 system and it failed in
configure with the following:
Checking for gcc:
  ** g++ (variable CXX) not found!
Check
/usr/ports/emulators/virtualbox-ose/work/VirtualBox-4.2.22/configure.log
for details
===>  Script "configure" failed unexpectedly.


configure.log is pretty short:
# Log file generated by
#
#   './configure --with-gcc=gcc --with-g++=g++ --passive-mesa
--disable-pulse -$
#

***** Checking environment *****
Determined build machine: freebsd.amd64, target machine: freebsd.amd64


***** Checking kBuild *****
found


***** Checking gcc *****
** g++ (variable CXX) not found!

# cat /etc/make.conf
WITH_NEW_XORG=YES
WITH_KMS=YES

# pkg info gcc-4\*
gcc-4.6.4

Of course, there is no g++, only g++46 on 10.0. Is this a configure error?
