Welcome to the PCLinuxOS forums. We're glad you're here.
If you have 2007 updated all the way through the 2009 updates, I should be able to help you. If you are using a recent install of 2007, it is very old in Linux time. Most users have newly installed one of the 2010 releases.
If your 2007 is fully updated, then you need to reload Synaptic. I can confirm the nfs-utils exist and is still in the 2009 repos. If you are tried to get up to date now, it will not work. Many changes have occurred.
If you need help getting a new version, or if you just mistyped, write back and someone will help you get going with PCLinuxOS 2010 and nfs.
