From your documentation, it is not really clear what is the requirements to setup Linux RedHat OS to install Web Agent. I would like to know for both architecture 32 and 64 bit.
The requirements for Linux RedHat OS for SiteMinder Web Agent and Policy Server are :
Web Agent R6, R12 and R12SP2 on ASF Apache
32-bit ASF Apache 2.2.x supported on RH 3, 4, 5 with Web Agent R6, R12.x 32-bit
64-bit ASF Apache 2.2.x supported on RH 3, 4, 5 with Web Agent R6, R12.x 64-bit
OS 32 and 64 bit, Redhat 4 and 5
NOTE : all previous requirements outside those one will be removed from documentation.
Apache 1.x, 2.0.x and 2.2.x Redhat 3, 4 and 5
Compiling is required because the Agent code uses pthreads (a library of POSIX-compliant thread routines), but the Apache server on the Linux platform does not, by default. You should set this environment variable first before compilation:
configure --enable-module=so --prefix=your_install_target_dir
