As far as I can tell the only use of /dev by the build scripts themselves is to write to /dev/null. The scripts are copied around and invoked via ssh, so there are pty devices being accessed too. I can't immediately think of anything else. The actual package builds (which may do other /dev operations) are done in a chroot, which has its own copy of /dev and is on a UFS filesystem on disk (/x), so that's apparently ruled out as being a factor here.
