I did find out how to get opencv installed on my raspberry pi, but I'm receving a new error - I will head over to the gitter chat after this post.
My fix to install OpenCV: "sudo apt-get install libopencv-dev"

I guess there is an issue with the libstdc++.so.6 with the current grip 1.3.0rc2 version or something. Also, it's straight out of jdk 8 throwing this exception specifically. --To Gitter!
Note: I will continue the updates on this thread as my problems are resolved, cheers!
