Problems installing Zabbix 1.4.1 from Ports on FreeBSD 6.2

[Soleil]

When I attempt to install Zabbix from Ports on a machine with PC-BSD 1.4 Beta (FreeBSD 6.2), I get the following error:

gmake[3]: *** No rule to make target `../../src/libs/zbxsysinfo/i386/libspecsysinfo.a', needed by `zabbix_server'.  Stop.
gmake[3]: Leaving directory `/usr/ports/net-mgmt/zabbix/work/zabbix-1.4.1/src/zabbix_server'
gmake[2]: *** [all-recursive] Error 1
gmake[2]: Leaving directory `/usr/ports/net-mgmt/zabbix/work/zabbix-1.4.1/src/zabbix_server'
gmake[1]: *** [all-recursive] Error 1
gmake[1]: Leaving directory `/usr/ports/net-mgmt/zabbix/work/zabbix-1.4.1/src'
gmake: *** [all-recursive] Error 1
*** Error code 2

I attempt to install Zabbix from scratch using "make install clean", without Apache HTTPD, PHP or MySQL installed first. As Ports should resolve and compile the dependencies, I do not presume that dependencies are the problem here.

Do you have any suggestions as to what might be the cause of and solution to the problem?
