Compile error: Curl library not found

[VeryNewbie]

Hi,

im trying to install Zabbix 1.4.3 on an AIX 5.3 (64bit).

I'm using the same configuration as on Zabbix 1.4.2 but i always get this error:

checking whether libcurl is usable... no
configure: error: Not found Curl library

when I check the logfile I get this:

configure:10385: checking whether libcurl is usable
configure:10430: cc -qlanglvl=extc89 -o conftest -g -I/tools/mysql/includ
