Maybe I'm doing something stupid, or this is a known thing, but I've been
unable to move forward in -current in the last few weeks.  I installed
originally on my AlphaPC 164SX from the 042098 snapshot, then moved to
-current around the middle of May.  But the last one or two weekend
tar_files bundles and now this (below) taking src from mid-week.  What
am I doing wrong here?

P.S. Like it is important or what, but I also lost my "system beep"
     when I moved from 042098 to -current.
