[gembud] GEMPAK 6.8 Questions

I have a couple quick questions about GEMPAK 6.8. 

I need to upgrade my OS X copy of GEMPAK TO 6.8 from 6.1. How do I do that? 
Just Un-Tar the file and re-make all and make install?

Also, I need to install GEMPAK in a CentOS VM (either version 5 or 6 x64 
depending on which version I can get going). Should I use the RPM or build from 
source? If I use the RPM, do I need to install all the prerequisites first or 
does the system automatically do that?

Thanks!
