Warning: Error parsing file...

[Michael Newman]

I recently had to reformat my boot drive, reinstall MacOS and restore from a CCC backup. After doing so I ran: 

sudo port -u upgrade outdated

And received many warnings like this:

--->  Scanning binaries for linking errors
Warning: Error parsing file /opt/local/bin/msgcmp: Error opening or reading file
Warning: Error parsing file /opt/local/bin/msgcomm: Error opening or reading file
<snip>

What should I do about this?
