[Serusers] Ser mysql Make error

I'm having a problem making the mysql module for ser. When I type make modules everything compiles fine except for the mysql.so, it returns an error saying: " /usr/bin/ld: cannot find -lz collect2: ld returned 1 exit status" If I remove the -lz it makes but can't be loaded correctly by ser. Any help would be greatly appreciated. Below is the makefile I'm using: # $Id: Makefile,v 1.22 2003/09/16 18:55:07 janakj Exp $ # # WARNING: do not run this directly, it should be run by the master Makefile include ../../Makefile.defs auto_gen= NAME=mysql.so # mysql.h locations (freebsd,openbsd solaris) DEFS +=-I$(LOCALBASE)/include -I$(LOCALBASE)/include/mysql \ -I$(LOCALBASE)/mysql/include -I/usr/pkg/include # libmysqlclient locations on RH/Suse, Solaris /OpenBSD, FreeBSD # (Debian does the right thing and puts it in /usr/lib) LIBS=-L/usr/lib/mysql -L$(LOCALBASE)/lib -L$(LOCALBASE)/lib/mysql \ -L$(LOCALBASE)/mysql/lib/mysql/ -L/usr/pkg/lib/mysql \ -L$(LOCALBASE)/mysql/lib \ -lmysqlclient -lz include ../../Makefile.modules Thanks for any help, Zack Medlin
