Just tried to run exiftool after installing Mavericks
exiftool AHC_6160.NEF
Can't locate Image/ExifTool.pm in @INC (@INC contains: /usr/local/bin/lib /Library/Perl/5.16/darwin-thread-multi-2level /Library/Perl/5.16 /Network/Library/Perl/5.16/darwin-thread-multi-2level /Network/Library/Perl/5.16 /Library/Perl/Updates/5.16.2 /System/Library/Perl/5.16/darwin-thread-multi-2level /System/Library/Perl/5.16 /System/Library/Perl/Extras/5.16/darwin-thread-multi-2level /System/Library/Perl/Extras/5.16 .) at /usr/local/bin/exiftool line 33.

I think I used the full installation of exiftool. I guess I should just re-install exiftool?
A fresh install seems to have solved the problem.
