I have committed a patch now that should fix th= is issue once and for all. http://svnweb.freebsd.org/ports?view=3Drevision&revision=3D336768 The analysis has shown that the vbox buildsystem has a strange check as part of their hardening that strips away rpath for Hardened-R3 binaries. It looks like that is supposed to protect against world writable RPATH paths which w= ould allow a user to inject malicious shared objects. Our gcc48 path is definite= ly a safe place so I decided to disable that check for FreeBSD. I will send that patch upstream and discuss the implications with the vbox developers to see if that has some additional risks.
