(In reply to hjf from comment #39)

Yes, I'm able to build it (using Poudriere), with or without disabling AIO.
However, as I said in comment #38, the latest official version does not work
for me.
Reenabling AIO is much better (I occasionally get AHCI timeouts in a FreeBSD
guest, but that's fine as I don't use vbox for anything too serious, at least
now; also, it probably did before, I'm not sure).

If you are having the problem I had (not sure, you don't tell), instead of
reverting to the previous version, you might just try the latest without
disabling AIO: use the following:
