  Yep, that's got to be the source of the problem.

  Gcc normally lives under "/lib/gcc-lib/....", rather than "/lib/gcc/...";
someone's been playing around with all the various individual --*-prefix=DIR
and --*dir= options at configure time, and got an inconsistent set.
Presumably they've got it installed under both prefixes on their development
PC because at some time in the past it's moved from one prefix to the other,
and so that hid the problem in testing. 

  Gerrit, is this your doing?

    cheers,
