lme4 dev github version

Hi,
Is the development version on github working properly at the moment? I 
cannot get it to work.
(I havent done this on a windows machine before so maybe im missing 
something)

fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy)
Error in .Call(merPredDupdateDecomp, Ptr, NULL) :
   Incorrect number of arguments (2), expecting 1 for 'merPredDupdateDecomp'
In addition: Warning message:
In fetch(key) : internal error -3 in R_decompress1

I mainly need the warning/conv slot available in the dev version. The 
version on r-forge repository (99999-8) has this function as well but 
the refit() function doesnt seem to work in that version. I get the error:
Error in stopifnot(length(newresp <- as.numeric(as.vector(newresp))) ==  :
   (list) object cannot be coerced to type 'double'
