RSA BSAFE- Cert-C,Crypto-C and ACE Client versions for RHAS 5

Hi
My application is currently working on RHAS3 with following versions of RSA components

BSAFE- Cert-C 2.7.2.0
Crypto-C 6.2.1.0
ACE Client 6.1

I need to port it to RHAS 4 and RHAS 5.
I am looking for versions of the above softwares which will work on RHAS4 and RHAS5. Also if there is a common version that will work.

Thanks
Geetu
