Failed to fetch dependancies, Failed to verify signature for archive!

[joel.gillespie.joel@…]

Yes I've read the many duplicate Tickets about signatures failing to verify, however I've tried this on multiple wifi networks and a data network, so its not a network error. I simply cannot fetch the dependancies needed for GPhoto2.

Please attach the main.log. Maybe it will provide more information about why this happened.

P.S: In case you did not know, we do have a port for gphoto2, so you don't need to install all the dependencies manually; you can just sudo port install gphoto2 and MacPorts will take care of it.
