It's possibly the issue that's come up on the forums: if you get something like: --- This is TeX, Version .... Fatal format file error; I'm stymied --- then you need to run 'updmap --all' (as the user you get this error with). Alternatively, you can delete the user's local texlive generated formats 'rm ~/.texlive/texmf-var/web2c/*.fmt' (then the system-wide generated formats will be used, and they do get regenerated automatically on upgrade).
