version to Irix 6.5

[Angelfn_Fastvi]

My name is Angelica Nunes and I work at TV Globo Rio de Janeiro/Brazil. 
I need some help about the SAMBA software. 

Our system is based on Silicon Graphics' machines, models: Indy, Impact, 
Onyx and Indigo using Operational System Irix 6.2, 6.3 or 6.4. We must
upgrade all these systems to Irix 6.5 version. We would like to know which
samba version is compatible with Irix 6.5?
Where do I can download it?
  
Thanks for your attention, 
Angelica Nunes
