You can't link libc statically (for glibc at least, other os' do allow it) 
any more.  I forget the last version that supported it, but it might well 
be prior to 2.4.  Either way, it's not considered supported to build 
against version X of glibc and run it against any version < X, only >= 
even if it happens to not link against a versioned symbol (not all symbols 
are versioned).
