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

# mysql.h locations (freebsd,openbsd  solaris)

                -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)

Thanks for any help,
