Just adding -ldl to the end of LDADDS in tests/Makefile.am fixes this problem for me, but I'm not sure if that is the correct way to fix it.
That sounds reasonable, if we're guaranteed always to have a libdl. However, the fact that it's not needed on F12 suggests that we should be adding it only when necessary (hence a configure-time test).
I hit that same problem a few hours ago, but haven't yet gotten to it.
I'm assuming that the problem is related to: http://fedoraproject.org/wiki/Features/ChangeInImplicitDSOLinking The virtualbox driver seems like it needs -ldl, but this was only being provided implicitly before, but now needs to be given explicitly.
