Installing New Libraries/Frameworks

[jmmistrot]

I am trying to add a new library to my system. I am really not to sure how to do this under OSX. I went in and looked at the directory structure and it is quite different than the Irix system i usually work on. My question is this:

How do I install a new framework/library?

Thanks,
