Hmm, did you really work with the 'lmer.R' source file instead
of just
   library(lme4)
or library(Matrix)  ?

Since Matrix has a name space -- as many other "modern" R
packages, you cannot just work with one (out of many) R source
files from the package.
If really want to use some of the package R source files,
you better use them all.
If you use
   example(source)
in R 2.3.0 ("or newer"),
you can subsequently use   sourceDir("..../Matrix/R")

Note that if this answer has been helpful, 
it means that your problem has not been related to "Mac" at all,
and you should rather have used the 'R-help' mailing list.

Can you confirm?
