I need help in using SCALAPACK

I want to solve a big (dense) linear system of equations that
results form the boundary element method (BEM).

My idea is to (block) distribute the matrix over a grid of processes 
(using BLACS or pvm),
initialize the describtions-vectors 
and then call the scalapack routine >> pdgresv <<

Badly, up to now I have no success.

Now my questions:
a) Is there a userguide (with examples) for Scalapack? 
   (I mean no installation guide)

b) Do anyone have experience with Scalapack/Pvm an could send
   me some easy examples?

c) Is the simple idea how I want to solve a big linear 
   system of equation wrong? 
   I.a. is it not possible to get the solution with a simple call of
   dpgesv?


Hoping for some suggestions
