Created attachment 386840 [details, diff]
Attached is a patch against the most recent ebuild to unbreak the totally botched release. The `chmod +x` trick is courtesy of Fedora , the find one is by me (I have no idea how come it works for them, files are from year 2159 here locally).
The PDSH_MODULE_LIST horrible hack which actively avoids USE_EXPAND is still there, I've had enough of this crap for today -- that waits for another brave soul.
Anyway, at least pdsh now respects my username prefs now...
