Port comparison failed

[Eric]

Anyone have a way to fix this:

<snip portsnap output>
Building new INDEX files... done.
portconf-1.2                        !   Comparison failed
portmaster-1.9                      !   Comparison failed

it happens when i run portsnap and then get new ports via:

pkg_version -v | grep \<

i tried uninstalling and then reinstalling the ports above but it didnt 
fix the issue.

I use portmaster to update ports. I do not have any other port 
management tool installed.

Thanks!

Eric
