It seems that new platforms also give problems, whether these are due to 
compilers remains to see. Problems also show up in other programs than 
mdrun. Running make distcheck verifies the distribution based on a CVS 
tree, and running the test set under different environments would be a 
first step to check the grompp/mdrun/pdb2gmx codes.

It seems that the real problem is to do this on many different machines, 
and how does buildbot help with this?
