--------------------------+--------------------------
 Latest released version of caffe is rc5 and the one provided through
 MacPorts is few years old already.

 I have already updated the Portfile and updated the patch files
 accordingly. I am facing some error related to opencv. Probably because
 opencv is by default built against python 3.x and caffe is trying to build
 it against python 2.7

 Attaching the patch and error log with the ticket.

 I would be happy to try to update the port.
