Unable to build virtualbox-ose after latest round up updates

[Kevin Oberman]

After doing all of the updates yesterday and today, mostly due to the icu
shareable version bump,  virtualbox no longer starts.It finds a symbol in a
library from qt4-gui missing.

I reinstalled qt4-gui and tried rebuilding virtualbox-ose, but the rebuild
fails with:

Any idea how to deal with this? Is anyone else seeing this?

Running 10-Stable r281259 with almost all ports up to date except chromium
(which should have nothing to do with this issue).

I really need to get my Windows 7 VM running again.
