auditing for RHEL ES4

I'm running RHEL ES 4 servers, and am having difficulty with aureport. I'm using audit version 1.0.15-3, the one that comes with the OS. The problem is that I need daily reports, and it is not doing it. The reports always cover the entire range of available logs (sometimes gigabytes of data). The reports can take a LONG time to compile, and it doesn't give me the daily snapshot I need. I'm thinking of installing the latest tarball and compiling, as I understand more recent versions of aureport have implemented time limits. [I've emailed this list before about this.] My question now is, is it possible to uninstall the prepackaged audit and audit-lib, and install the latest from source, without seriously hosing my system?
