Oddly enough perhaps yes, since though the patch is mostly for
MacOSX, it provides additional compile-time tuning on other platforms.

Your system does not have a "postdrop" group.

Well, "maildrop" is not "postdrop".

You can either create a "postdrop" group, or with the patch re-use the
existing "maildrop" group, which makes it easier to transition between
the system and your custom Postfix, since file permissions will be the
same. I recommend the latter:
CCARGS='... -DDEF_SGID_GROUP=\"maildrop\"'
