I've not seen that error before, but here are some random thoughts:

Does your vistVtx virtual disk work okay with the prebuild i.e. are you
using the same .vdi file with both?

What compiler are you using?  Any custom CFLAGS or CXXFLAGS?

Maybe you'll get some less random thoughts from the devs :o)
