From 024bd68f643d2d915f6a6b769bf278480d241fa7 Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Tue, 15 Oct 2013 14:46:24 -0700 Subject: [PATCH] wic: Check for external modules Since eight unique files import rpm, perform a check at the top level for the existence of the rpm module print a sensible error message if it is not. This may be able to be removed if some of the core rpm dependencies are removed from the mic libs. Also check for urlgrabber. This avoids a bracktrace in the event the modules are not installed which can be very off-putting to would-be users.
