-==== Problem with pypar Installation ====

-We have been seeing the following error when trying to import {{{pypar}}}.

->>> import pypar

-
-For us this was caused by there not being a file {{{libmpi.so.0}}} in the {{{/usr/lib}}} directory. This is really a {{{pypar}}} bug, but as a work around we created a link from the file {{{/usr/lib/libmpi.so}}} to {{{/usr/lib/libmpi.so.0}}} via the command
-
-{{{
-sudo ln /usr/lib/libmpi.so /usr/lib/libmpi.so.0

-
-Then {{{import pypar}}} should produce the following
-
-{{{
->>> import pypar
-Pypar (version 2.1.4) initialised MPI OK with 1 processors

 By the way, it is sometimes useful to fire up a new console to see if these 
 installations work in a clean console.
