When doing 'make patch' in wip/scummvm-nightly, one gets:
...
=> Applying pkgsrc patches for scummvm-20080218
-p: not found

This comes from mk/patch/patch.mk around line 300:
                        if ${_CHECKSUM_CMD} -p ${DISTINFO_FILE} $$i
_CHECKSUM_CMD is not defined, because wip/scummvm-nightly is using
svn-package.mk and thus doesn't use a distinfo file for the distribution
file; however, it has a patch.
>How-To-Repeat:
cd /usr/pkgsrc/wip/scummvm-nightly
make patch
