I bet it's the "-q". For what it's worth, I build with source and
objdirs on NFS mounts all the time, mounted with "-3Tbi". Try it
without the "-q".
It's not even clear from the man page what "-q" does. It's a backport
of the leasing extensions to version 3 to version 2 + NQNFS? What if
you're using version 3?
