Function generate_dep_list is creating a DEPLISTFILE
with a lot of unwanted 'installing package xxx' messages
when it should only contain a list of unresolved
dependencies.
On the next iteration we waste a lot of time trying to install
nonexistant packages 'installing' and 'packages', and re-installing
packages we already have.
Instead of converging on an empty DEPLISTFILE, we converge
on a DEPLISTFILE that just reiterates the same list of
'installing package' if we are lucky, which we usually are,
but not always.
