Right. Virtualbox is special in that it builds a kernel module so it needs to build for the architecture of kernel your computer runs.

The architecture of kernel that the Snow Leopard buildbot runs is apparently x86_64, so it does not build the dependencies universal. But on your computer the kernel is i386 so on your system you need universal dependencies.

Nope, everything seems to be working as intended. Virtualbox says it is not universal, which is the truth. But when built 32-bit on an otherwise 64-bit system, it needs universal dependencies, no different from any other port in that situation (wine, wxwidgets, etc.).


To the heart of the matter: I agree it would be a good idea if we could get the buildbot to always attempt a universal build as well. I don't know what would need to be changed about the buildbot configuration to get that to happen however.
