[R] RMySQL installation: libz missing

[Christoph Lehmann]

Hi
I run suse linux 9.1 and I installed MySQL server, client, devel, bench.
DBI is installed, when I try to install RMySQL I get an error saying, 
that libz is missing.

(paths to libs were set:export PKG_CPPFLAGS="-I/usr/include/mysql/"
export PKG_LIBS="-L/usr/lib/mysql/ -lmysqlclient")

so my question: where do I get the libz files (are these mysql files? if 
yes, why were they not installed at least by mysql-devel?)

thanks for your kind help
