The original Makefile contained DOS line endings in it, which although my patches could deal with fine they got lost in the original posting and rendered the original patch unusable.
So i just decided to fix the problem at the source and modify the actual distfile Makefile and remove the Makefile patch all together. Below (and in the attachment) are the new diffs. Now portcheck also completes with no issues.
