Hi Bill, Sorry for taking so long to respond. I tried running the scripts again in the different conda environments (with and without Trilinos) and do indeed get the same error as you. I probably didn't switch environments properly when I tried this before. Anyway, I think I've fixed the issue, the changes I made are
http://matforge.org/fipy/changeset/b7246011a00584b5e6757404b2b51ca47d71004a/fipy/ and the ticket http://matforge.org/fipy/ticket/669 You'll have to fetch from the main repository and checkout the ticket669-pickle_comm branch to got these changes if they are important to you.
