This does not seem to be an unreasonable guess, particularly if
any of the library major version numbers bumped on the 1.6 branch
post 1.6.2.  I'm not entirely sure how to check this.  I did

tar -ztvf base.tgz | grep usr/lib/ | grep -v "\->"

on both base.tgz and comp.tgz, and manually confirmed that there
was no /usr/lib/*.so.x.y with a greater x for any of the results,
and that is true.  But I'm not sure I'm catching everything.  Is
there an easy (or at least sure, if not easy) way to check this?

It happens in two spots (during kernel compile):

Note the odd line starting with


in the second example.  I got the above from

make -dA 2>&1 | split

I'm not sure if that's a problem with buffering, or what, but
... it's what I got.

As always, any suggestions are appreciated.
