OK, I see. I guess because of this fragility, there is no hope of 
running standard universe in Ubuntu using research.cs.wisc.edu Debian 
packages. I am more and more interested in trying DMTCP again :-)..

It's some time ago already but I think the main two problems were mix of 
32/64 bit software and using an external file (not transferred using the 
standard mechanism, e.g. very large data files).

The background of the first problem was that we had some 32 bit software 
and our system is 64 bit. Normally compatibility libraries work without 
a problem but DMTCP did not allow that. I think specifically it would 
have worked if all binaries would have been 32 bit (including the shell 
when running a shell script and DMTCP binary itself) but that would have 
been bit too much of work. Perhaps these limitations have been lifted 
already.
