shells/fish fails to install due to checksum mismatch.

[Mike Roberts]

shells/fish/Portfile specifies a checksum of 
522fba3b00939f9c36f2eac14ffc10a6 but i downloaded the package myself 
(from fishshell.org/files/1.21.11) and found that the checksum should be 
a4cf3dc089f819fe806644f7cb8dcf11.

also, while trying to determine the md5sum of the package, i discovered 
that the md5sum command appears to be missing from the corefiles port. 
"info corefiles" suggests that it should be present but i cannot find it 
in /opt/local/bin.
