The very ones I found in the handbook (except substituting gs-sources for 
gentoo-sources):
# emerge gs-sources
# ls -l /usr/src/linux
lrwxrwxrwx 1 root root 24 Apr 23 10:21 /usr/src/linux -> 
linux-2.4.25_pre7-gss-r3
# cd /usr/src/linux
# make mrproper (although this wasn't in the handbook, the README says to, 
so I did)
# make menuconfig
# make dep
# make bzImage
# make modules

Yes.

make mrproper whacked my .config.bak, but I had another copy elsewhere.

# cp -i /root/2kernel.config .config

Thanks for the reply, John, but I'm still stuck with the same problem.  It 
sure seems like I'm missing a .h file somewhere.  Has something changed 
in these kernel portage packages recently?  I don't remember getting this 
problem the last time I did a stage 1 install of gentoo on a different 
box.  Can someone try to replicate this problem by following the handbook 
and doing a stage 1 install themselves?  I realize that's alot to ask, 
but this sure seems like a big problem here.  I did nothing out of the 
ordinary.  The device mapper kernel patch is clearly included in the 
gs-sources package, but is everything from it completely included?  Not 
so long ago, a downloaded a vanilla kernel from kernel.org and patched it 
with the device mapper patch myself, and then built it with no problems.

Any other suggestions?  Anyone?

Thanks very much.
