Deleted /lib directory... How to restore from LiveCD, etc?

Hello,
After many years of Linux use I was rebuilding a kernel on my laptop and was removing some old /lib/modules/kernel files and fat fingered it.
Ah well...
Does anyone know of a way to rebuild the /lib directory? I have a another desktop running Gentoo, as well as a LiveCD, & a Knoppix CD..
Can I CHROOT, copy the /lib directory over from the LiveCD and then rebuild the Kernel?
Many Thanks!

That's sort of the problem with Gentoo - you may not be able to steal binaries from another box and expect them to work due to differing USE flags. Ideally what you have to end up doing is taking your world file, your make.conf and USE flags, and rebuild all those files in /lib using a recovery CD as if you were starting from scratch again. Probably could swipe the /lib directory from a stage3 to start from to at least start that going again.

Thanks for the reply!
I ended up copying the /lib directory from the livecd. That got me going (with a lot less errors than I had) Bash complained about everything.
I then rebuilt the kernel, re-emerged portage & bash from the CHROOT'd environment.
Rebooted to the HDD and logged in as normal.
I then re-emerged gcc,glibc, & libstdc++ and rebuilt the kernel, again, against the newly emerged compiler...
Temporarily added GCC,glibc, & libstdc++ to package.mask and emerged -e system & emerged -e world.
Still going on the world emerge, but all seems fine for now.
Guess that'll teach me for using my fat fingers while typing.
I'm sure there was an easier way, but this got me going and it got the system back into a good state of health.
Best Regards
