libgphoto2 ebuild depends on three usb packages: dev-libs/libusb sys-apps/usbutils sys-apps/hotplug Neither of them is actually required on non-usb systems; those dependencies should therfore be controlled by an use-flag (usb?). Reproducible: Always Steps to Reproduce: 1. 2. 3.
Created attachment 36396 [details, diff] libgphoto2-2.1.4.ebuild patch adding usb useflag
the patch is fine (except it's reversed :) however, i'm relucant to add this because most cameras have USB interfaces and secondly, because usb isn't in the default use flags, it will be turned off by default. that is not a good default to have, i'd rather have a nousb USE flag instead.
fixed in 2.1.5
