It took me a while to find why "port outdated" was failing.
I had a port installed that had revision set to and empty string.
I doubt this is a common problem for developers but I mention it in the case
that a test to verify that $installed_revision and $latest_revision are numbers
would be worthwhile.
/opt/local/bin/port:912
if { $comp_result == 0 } {
set comp_result [expr $installed_revision - $latest_revision]
}
