How to install synergy on RHEL5?

I'm trying to build from source using CMake as recommended (http://synergy-foss.org/pm/projects/synergy/wiki/Compiling) [d3p299@we16410 synergy-1.3.7-Source]$ ./hm.py build Running setup... Error: Generator not specified, use -g arg (use hm genlist for a list of generators). So I lsit the generators: [d3p299@we16410 synergy-1.3.7-Source]$ ./hm.sh genlist 1: Unix Makefiles 2: Eclipse CDT4 - Unix Makefiles Ok I need index 1, so I try: [d3p299@we16410 synergy-1.3.7-Source]$ ./hm.py build -g 1 Error: option -g not recognized Maybe the syntax of the command is wrong? [d3p299@we16410 synergy-1.3.7-Source]$ ./hm.py usage Usage: ./hm.py [-g |-v|--no-prompts|] Example: ./hm.py build -g 3 I am running the command correctly as suggested in the help command. What gives?
