[gentoo-user] Downgrade glibc-2.11 to 2.10

[Alan McKinnon]

Yes, I have read this in 
/var/portage/sys-libs/glibc/files/eblits/pkg_setup.eblit
and I understand the risks.

if has_version '>'${CATEGORY}/${PF} ; then
  eerror "Sanity check to keep you from breaking your system:"
  eerror " Downgrading glibc is not supported and a sure way to destruction"
  die "aborting to save your system"
fi

I want to do it anyway.

A multitude of apps that used to run just fine now give "free(): invalid 
pointer" errors since I upgraded to glibc-2.11

A simple downgrade doesn't work - too many apps will not start including bash. 
Has anyone done this or knows of a howto? I'm happy to rebuild a few critical 
apps statically if that's what it takes. I'm not happy chasing down half the 
system to do it :-)
