Bug report: linux_base-8 cannot upgrade through NFS

[Enoch W.]

Hi,

This started a number of revisions ago.
It has become impossible to upgrade from a ports collection that is NFS 
mounted.
The error message is:

===>  Installing for linux_base-8-8.0_6
cannot get exclusive lock on database
kern.fallback_elf_brand: -1 -> 3
redhat-release-8.0-8.noarch.rpm
cannot get exclusive lock on database
error: cannot open 
/usr/ports/emulators/linux_base-8/work/linux_base-8-8.0/var/l
ib/rpm/packages.rpm
*** Error code 1

Is there a solution except for copying the ports to a local drive?

Thanks, Enoch.
