Comment (by jeremyhu@…):

 Please narrow this down to determine if the issue is from ld64 or cctools.
 I think deactivating the old version, activating the new one, and using
 'port install virtualbox' instead of 'port upgrade virtualbox' will handle
 that.

 Additionally, please check if the issue exists with just our version of
 that port or if the issue exists in XCode 4.5.1 as well.  You can force
 apple-gcc42 to use XCode 4.5.1's linker by changing this symlink:

 /opt/local/libexec/apple-gcc42/gcc/i686-apple-darwin12/4.2.1/ld

 By default, that symlink points to ld provided by the ld64 port, but try
 removing it and replacing it with a link to /usr/bin/ld (make sure you
 have the latest version of Developer Tool's Command Line Tools installed
 or you may have the XCode 4.4 version despite having XCode 4.5 installed).
 You can similarly force XCode 4.5.1's assembler by modifying the as
 symlink instead of the ld symlink.
