Compilation error on HP-UX 10.20

[steria]

Hello,

I am trying to install zabbix 1.4.1 agent on a Solaris 2.5.1 server.

The configure command runs fine:
./configure --prefix=/usr/zabbix --enable-agent

However, when I run make, I get the following errors:

Making all in zbxsys
        source='mutexs.c' object='mutexs.o' libtool=no \
        DEPDIR=.deps depmode=hp /usr/bin/posix/sh ../../../depcomp \

Any ideas?

Does anyone managed to install zabbix agent on a HP-UX 10.20 platform ?

Thank you very much.
