Binary and source packages of recent versions of the development versions lme4a and lme4Eigen are available here (under development). When it is up and running, you should be able to install these versions either by descending through the directory hierarchy to find the appropriate versions, or via (e.g.)

install.packages("lme4a",repos="http://lme4.r-forge.r-project.org/repos")
install.packages("lme4Eigen",repos="http://lme4.r-forge.r-project.org/repos")
Note that you may have to install dependencies (e.g. RcppEigen and minqa for lme4Eigen) for other repositories first. If you don't find what you need here, please contact the maintainers.
