Checksum issue with pkg-1.6.0

[Scott Allendorf]

Since upgrading from pkg-1.5.6 to pkg-1.6.0, I have been receiving many 
checksum mismatch messages when running 'pkg check -sa' on multiple 
recent stable/9 systems:

...
perl5-5.20.3_8: checksum mismatch for /usr/local/bin/perl5
perl5-5.20.3_8: checksum mismatch for /usr/local/bin/perl5.20.3
perl5-5.20.3_8: checksum mismatch for /usr/local/bin/perlthanks
perl5-5.20.3_8: checksum mismatch for /usr/local/bin/pstruct
perl5-5.20.3_8: checksum mismatch for /usr/local/bin/s2p
...

These files passed the checksum check prior to upgrading to pkg-1.6.0. 
The only change to the installed ports was the pkg upgrade.

It appears that reinstalling the affected files corrects the checksums. 
  Did the checksum algorithm change in some subtle way that would cause 
some, but not all, files to have different checksums between versions 
1.5.6 and 1.6?

Please let me know if I can provide additional information.

Thanks,

Scott
