problems building virtualbox-ose with gcc4.7

[Anthony Brown]

Hi
   I am running 10-Release on amd64 and had problems build virtualbox-ose -
it failed with this error

kBuild: Generating
/wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-4.3.8/out/freebsd.amd64/release/obj/Runtime/errmsgdata.h
/usr/local/bin/kmk_sed: file
/wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-4.3.8/src/VBox/Runtime/common/err/errmsg.sed
line 31: Unmatched [ or [^


I finally tracked this down to the fact that the kBuild port I was
using was built with gcc4.7


   I changed the Makefile for kBuild to have

USE_GCC=        4.6

rather than

USE_GCC=        any

   rebuilt and reinstalled kBuild and then virtualbox-ose built fine

   Is this a known problem, and if so can the Makefile for kBuild be
changed to use gcc4.6

Thanks

Anthony
