My hunch now is that the package brought with it an .elc file (probably
magit.elc) compiled with the wrong Emacs version. Removing all .elc and
recompiling the directory seems to succeed (I've ditched magit now for
anoter reason -- it doesn't like my git 1.7.x and wants 1.9.x, I'd have
to resort to an older magit, sigh). I'll try to verify (or falsify) my

Your proposal suggests that you have a similar hunch as mine :-)

Perhaps there should be a way for Emacs to find out that an .elc file
doesn't match the current binary interface (I've been stumped by
"wrong" .elc files (i.e such compiled by an Emacs with different
byte code conventions) more than once).

I'll ponder a bit on it. Perhaps I can offer more than just some
half-smart mumblings :-)

Thanks for your work -- and your insightful comments!
