If anyone in the world aside from me wants to get the development version of lme4 from http://lme4.r-forge.r-project.org/repos/src/contrib/ working on Fedora 18, with the Fedora rpm version of R (not yet updated to 3.0), you have to re-install the minqa package, in addition to updating the usual ones such as Matrix.
