error during first run: Error: no `server' JVM at .... libjvm.so'.

I've installed the product without issue, upon first start I get the below error:

========================
netflow@netflow:/opt/NetFlow$ cd bin
netflow@netflow:/opt/NetFlow/bin$ ./run.sh

--SNIP--

First time service startup takes longer time than usual
Error: no `server' JVM at `/opt/NetFlow/jre/lib/i386/server/libjvm.so'.
netflow@netflow:/opt/NetFlow/bin$

=======================

/opt/NetFlow is a NFS export which we mount on the machine 'netflow', I didn't see anything in the docs about not using NFS mounts so i'm assuming this isn't the issue.

netflow@netflow:/opt/NetFlow$ id && ls -l ../
uid=1390(netflow) gid=1390(netflow) groups=1390(netflow)
total 26
drwxr-x--- 17 netflow 10001 569 2011-04-04 13:32 NetFlow
netflow@netflow:/opt/NetFlow$

any idea?
thanks,
greg
