I was hoping to use gphoto2 to capture images from a DLSR camera. I imagined using "Execute Shell Command" node to do this, however I get the following error

"dyld: Library not loaded: /opt/local/lib/libgphoto2.6.dylib Referenced from: /opt/local/bin/gphoto2 Reason: no suitable image found. Did find: /opt/local/lib/libgphoto2.6.dylib: file system sandbox blocked stat()

I imagine this is some security limitation. Any way around it, noting of course that the command I'm using works in the Terminal.
