Thanks for all replies.
I ended up exporting "distfiles" and "pkgsrc" as two NFS-shares (pkgsrc
read-only), setting "DISTFILES" and "WRKOBJDIR" in every /etc/mk.conf.
So each machine now builds locally on its own but stores downloaded
distfiles in a central place.
Sure, central working directories (well, per arch) speed up things but as
I am not sure how this will behave in situations where configure-scripts
detect different results on different machines (WILL it run configure in
any case or just leave out the "build" and do the "install" only?), I
prefer the setup I use now.
I know there might be race conditions with the distfiles, but as I use to
install a new package on only one machine first, this should be no
