I just had the same thing happen to me on the 23rd except that I could not
complete the build after rebooting. I was also building in an NFS-mounted
/usr/ports dir and it hung at exactly the same point. Looks like more NFS
garbling again. I was in X at the time so I couldn't get into DDB to get
a crash post-mortem.
