compile problem on hpux with zabbix 1.8.x and 1.9.8

[hpcre]

hey
i have been hitting into a compile error on both aix and hpux regarding the iconv not found problem.
i manually edited the configure script to bypass those checks.

I have another problem during the actual make..
i get the following error

gcc  -g -O2    -static  -o zabbix_agent zabbix_agent.o stats.o cpustat.o diskdevices.o perfstat.o vmstats.o zbxconf.o ../../src/libs/zbxsysinfo/libzbxagentsysinfo.a ../../src/libs/zbxsysinfo/hpux/libspecsysinfo.a ../../src/libs/zbxsysinfo/common/libcommonsysinfo.a ../../src/libs/zbxsysinfo/simple/libsimplesysinfo.a ../../src/libs/zbxlog/libzbxlog.a ../../src/libs/zbxalgo/libzbxalgo.a ../../src/libs/zbxsys/libzbxsys.a ../../src/libs/zbxnix/libzbxnix.a ../../src/libs/zbxcomms/libzbxcomms.a ../../src/libs/zbxconf/libzbxconf.a ../../src/libs/zbxcommon/libzbxcommon.a ../../src/libs/zbxcrypto/libzbxcrypto.a ../../src/libs/zbxjson/libzbxjson.a ../../src/libs/zbxexec/libzbxexec.a  -lm
ld: Can't find library for -lunwind
Fatal error.
collect2: ld returned 1 exit status
make: *** [zabbix_agent] Error 1

I cant find anywhere anything suggesting how to get out of this mess.
I really am wondering how anyone managed to compile their binaries on aix / hpux !!
