Hi, I've tried to make png-1.2.23, but with this result:

----------
bash-3.2# sudo make
=> Bootstrap dependency digest>=20010302: found digest-20070803
===> Checking for vulnerabilities in png-1.2.23
checksum: Checksum SHA1 mismatch for libpng-1.2.23.tar.bz2
ERROR: Make sure the Makefile and checksum file (/usr/pkgsrc/graphics/ 
png/distinfo)
ERROR: are up to date.  If you want to override this check, type
ERROR: "/usr/bin/make NO_CHECKSUM=yes [other args]".
*** Error code 1

Stop.
make: stopped in /usr/pkgsrc/graphics/png

I've deleted "/usr/pkgsrc/graphics/png" and made "sudo cvs -q update - 
dP", again with same result. Any suggestions?
