  I haven't checked, but I *think* that the development version
of lme4 (formerly lme4Eigen) now dominates lme4a -- and it works
on this example.  If there are things that you want to do that 
lme4a does that the development (r-forge) version of lme4 *doesn't*
do, please let the maintainers know and we will fix them ASAP ...
