Yes, I know that.

A very interesting PDF. Thanks very much.

I'm not a developer. I have one machine which is equivalent to all other servers except that it has gcc, make and some
otherthings for me to build PostgreSQL. I can't make the admins run a rpm on all servers. I can obviously put a library
intothe /path/2/postgres/software/lib64 directory but not into the system. 

Also, my build server does not have internet access. So things like git clone would be an additional show stopper.
Unfortunately,I'm pretty limited. 

Cheers,
