The upstream package of cscope has been changed to fix CygWin bugs, and the maintainers did not bump the package version, so the port build fails with "checksum mismatch" Fix: Apply this patch:
Responsible Changed From-To: freebsd-ports->petef over to maintainer, with a couple of remarks: if both distfiles are equally usable, then it would be good to leave the old MD5 hash in the distinfo file, so that the port skeleton will continue to work for people who already have the old distfile. Also if there are no significant differences for FreeBSD users, the PORTREVISION need not be changed.
State Changed From-To: open->closed Fixed, thanks -- I just added the new checksum + didn't bump the PORTREVISION, like trevor suggested.
