backend changes (2nd attempt, this time it works without getbinpkg):
* portage binpkg fetcher seem to be buggy and unreliable since v2.3.40 also, it's weird they implemented it as an os.call to wget, instead of a proper python method * implement our own binpkg fetcher, written in python, and bypass buggy portage one * as a drawback, installation time may become slightly longer portage downloads in background and starts installation right away our new method will allways wait for the download to be complete before it starts to install...but hey, at least I won't get bugged every day about portage bugs
