Well, I can't tell from your explanation whether or not this is your
problem, but I think I have seen this before when moving from one
Unix BSD platform to another Unix Platform. SOmetimes the /etc/export
file must define a "mount point file system" that is no sub-directories
(for example if /usr is a file system you cannot define /usr/proj in
/etc/exports). Under other implementations that is allowed (although
the first case is perfectly compliant with Sun Specs).

Hope this can help ....
