I think that documentation is pretty old (years old).  What you need is 
glibc--I don't think libpthread is even packaged separately any more.  (I 
just check.  It isn't.)  Make certain you have glibc-devel installed too.

For documentation, I refer you to any pthreads book.  There are some minor 
differences between the posix thread specification and linux pthreads 
implementation, but you'd need to get pretty deep to notice them.  (And 
supposedly they will be come come 2.6, and maybe even in RH 9!)  The main 
thing to note is that each thread will appear as a process when you run ps 
or top.  You can't send a signal to the process as a whole, only to a 
specific thread--and that is the only real difference I know of with 
pthread and linux threads.
