So what can I do to fix this? I've upgraded to nfs-utils-1.1.4 in the
meantime, 1.1.5 and both 1.1.6 give me

with
./configure --prefix=/usr/local --sysconfdir=/etc --with-tcp-wrappers=/usr/include --with-statedir=/var/lib/nfs
I've already upgraded tcpd to the Lenny version 7.6.q-16 (from
source), but that didn't help.
With 1.1.4, I still get 16384 [rw]size while 32768 were requested.
