Hello,
I'm not able to install anything via mac ports, see code below:

sh-3.2# port install wireshark

sh-3.2# port remove checksum
Unrecognized action "remove"
sh-3.2# port uninstall checksum
Error: port uninstall failed: Registry error: checksum not registered as installed.

It cant calculate md5 sum, whatever I install md5 sum is wrong, not just this package. How do I remove checksum program and reinstall it again> it seems it is malfunctioning.
