Well, that's ofcourse a problem...

portmap usually logs to syslog, it should therefore appear in 
var/log/messages and/or  /var/log/syslog unless your syslog 
configuration removes it. Well I would do:

/etc/init.d/portmap stop
/sbin/portmap -dv

which should spew stuff onto standard output.

Well apparently we use the nfs-kernel-server (ii=install,installed) and not the 

nfs-user-server (pn=purge,not installed).

This is a significant difference.

Did you consider switching to the nfs-kernel-server ?
