The Rforge is not mapping libgfortran correctly hence the error. You can work around that by installing gfortran from CRAN - but please read on instead.

I have created extra "untested" repository for this, you can now install lme4 (CRAN version but ignoring check failures) using

install.packages("lme4",,"http://r.research.att.com/",type='mac.binary.untested')
