I just realized there was a misunderstanding here.  The recompile opera-
tion I was trying to do was on the installation that resulted directly
from the four distribution CDs, which were of SL 4.2 and used kernel
2.6.9-22.0.1.EL.  The source tree I had was entirely what was put there
by the install procedure, so the missing files were missing because the
install never put them there.

I'm considering building a new source tree out of 2.6.9-34.0.1.EL.src.rpm
precisely to get past this omission.
