Can't run openoffice on amd64

[Stroganov A. V.]

Hi.
I've downloaded latest package of OOo for FreeBSD 6.1 for amd64 from
good-day, installed it, but it doesn't run, saying 3 times:
/libexec/ld-elf.so.1: /usr/lib/libstdc++.so.6: unsupported file layout

any advice?

uname -a:
FreeBSD savs.home 6.1-STABLE FreeBSD 6.1-STABLE #1: Tue Jul 25 10:34:37
MSD 2006     sav at savs.home:/usr/obj/usr/src/sys/CUSTOM  amd64

Thank you.
