kde compile failure

[blamothe]

i am trying to emerge kde and this error keeps coming up:

libtool: link: warning: `-version-info' is ignored for programs
g++: /usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.1/libstdc++.so: No such file or directory

!!! ERROR: kde-base/kdelibs-3.1-r2 failed.
!!! Function kde_src_compile, Line 117, Exitcode 2
!!! died running emake, kde_src_compile:make

i am running a p4, and the relevant make.conf info is:

USE="X gtk -cups kde qt gnome mmx -quicktime"

CFLAGS="-march=pentium4 -O3 -pipe -fomit-frame-pointer"

I don't get the problem. what should i do
