How did you re-install Matrix?
Your version   Matrix_0.999375-17  (indicated below)
is a bit old, and indeed probably too old for the version of
lme4 you've tried.
Can you call
    packageDescription("lme4")
without an error {probably not}, or at least

    library(help = "lme4")

the output of these would show you the version of Matrix you
need at least.

Ideally you'd upgrade your version of R (to 2.9.0) as well,
since the latest couple of versions of Matrix all have 
"R >= 2.9.0" in their dependency requirements.
