Show the packages found when installing at DEBUG level.

When attempting to ensure all desired packages at the
right versions are still findable not only print out
that we could find them, but also DEBUG the
information retrieved about the package, which will be
useful in cases where someone wants to look at the debug
output to verify whats going to be installed.
