thanks to

get LIBREOFFICE
LibO_3.3.2_Linux_x86_install-rpm_en-US.tar.gz

then search by bash:

# for i in `ls `
> do
> echo ----------------------------- $i
> rpm -qlp $i
> echo
> done | less

found libreoffice3-ure-1.7.0-202.i586.rpm

so
# rpm2cpio libreoffice3-ure-1.7.0-202.i586.rpm | cpio -id
then found the so file in
/opt/libreoffice/ure/lib
check for sure
# strings libstdc++.so.6 | grep GLIBCXX
shows the specific version.

then locate it by 755 to a proper location (on LDLIBRARYPATH?)
