[Bioclusters] Need some help with MrBayes and mpi

I experienced the same problem as described here. I solved the problem
by removing the "log" command from the bayes block of my nexus files.
I don't think mpich likes the command. Just in case it helps anyone.

The problem is in the reasembeling of the tree file. I've tried to fix 
the bug, but without luck. I suspect it
has something to do with stalled data in NFS.
There is a new version at mrbayes.sf.net I haven't tried it yet but it 
might fix the problem.
