The platform-freebsd.cc change looks good to me (for now, please use
the arch=x64 option to scons to build the 64-bit version - we will
update the architecture guess soon).  Before I can put back this
change, I need you to sign the contributor license which can be signed
electronically here:
http://code.google.com/legal/individual-cla-v1.0.html.

For future patches, please follow the guidelines at
http://code.google.com/p/v8/wiki/Contributing on uploading changes for
review.

Thanks for the patch!
