"Tk and Tk::JPEG version must be the same" --Stephen Lidie
"Please ask ActiveState to update the Tk::JPEG ppm." --Slaven Rezic
I suggest that you try to install Tk::JPEG on your box via the CPAN shell, and send an email to activestate asking them to update their Tk::JPEG.ppm file because their Tk and Tk::JPEG ppm's are out of sync, which *is* their fault.
