AIX 5.3 build

I am trying to build cfengine-2.1.21 on an AIX 5.3.0.0 JS21 system.
This is my configure command.
./configure --with-berkeleydb=/usr/local/BerkeleyDB.3.2

Can someone tell me what I need to do to get a good build, please?

We have it working now. Did a remove of gcc compiler that was in
stalled from the toolbox on the default 5.1 version. Then did a manual
install of the 5.3 Gcc rmp compiler that is on the toolbox CD.
