I set a raspi up so I could find out the issue BillC and others have been having recently regardin OpenCV running in MRL.

The latest versions of MRL uses OpenCV 2.4.10 ...  

Going to 2.4.10 is great - new features and such BUT - it appears Samuel @ JavaCV does not have an arm linux binary set ... only android arm :(

The quick fix is to do a build on a raspi and package it up and put it in the repo .. 

The long time fix is to get another project created in github which does all the native builds - for opencv, rxtxlib, joystick and any other native dependency ..
