lme4a is under active development and I will often commit things from
work then update at home, add some more code, and commit again.   My
standard for commits is that I can run

R CMD INSTALL lme4a

on an Ubuntu 64-bit system, which I run both at home and at work.  I'm
not surprised that it doesn't compile and pass checks everywhere.
Things will need to stabilize with a week because I have project
reports to read and grade starting next Tuesday and I won't have time
for further development.
