gzip: compressed data not written to a terminal error in rebuilding openoffice.o

[paulajulienne]

I am rebuilding openoffice.org in kubuntu dapper, I was able to build it at first, but after I tried to rebuild it again it pru\oduces this error:
gzip: compressed data not written to a terminal. Use -f to force compression.
I've tried upgrading gzip, but it's no use....
Does anyone know how to resolve this error? I will really appreciate your help.
Thanks.
Please see the output below:

find debian/openoffice.org-$i -type f -name "*.1" | xargs gzip -9; \
done
