Error in lme4 0.999902344-0: "Object 'multResp' not found" ?

Dear list,

The simplest random intercept model that I try to fit with the newest version of lme4 (0.999902344-0) throws an "Object 'multResp' not found" error on my Mac (Mac OSX 10.7.3, German R 2.15.0). Here is a reproducible example:

install.packages(c("minqa", "Rcpp"))
install.packages("lme4", repos="http://lme4.r-forge.r-project.org/repos")
library(lme4)

my_data <- read.csv("http://dl.dropbox.com/u/5384027/my_data.csv")
my_data$group <- as.factor(my_data$group)

# the data set consists of 97 four-person teams
# with two variables x and y observed on the individual
# level in each team

head(my_data)
# ? X group ? ? ? ?y ? ? ? ? ?x
# 1 1 ? ? 1 2.914286 ?-8.170984
# 2 2 ? ? 1 2.746269 -13.504318
# 3 3 ? ? 1 3.171429 ?-1.504318
# 4 4 ? ? 1 2.978723 ?-4.837651
# 5 5 ? ? 2 2.928571 ?-8.170984
# 6 6 ? ? 2 2.987013 ? 8.495682

mlmodel1_ri <- lmer(y ~ x + (1 | group), data = my_data)

# Fehler in lmer(y ~ x + (1 | group), data = my_data) :
# ? Objekt 'multResp' nicht gefunden

Does anyone know how to fix this?

Not a problem on an Ubuntu system.  It may be something to do with the
version of the Mac OS X package on R-forge.  Ben is the person who
creates those and he is very busy right now with teaching obligations.
 Do you have the capability of compiling the source package?

Here are the results on an Ubuntu 12.04 system

thanks for the notification.  I've just posted 0.999902345-0
to the repository (it may take up to 24 hours to appear), should
address this issue.
   I've also updated the source version on the repository
(i.e. http://lme4.r-forge.r-project.org/repos ) to this
version; the Windows version is a bit older, but current
source and Windows versions (unlike MacOS) should be available
from the standard package directory at http://r-forge.r-project.org
(i.e. install.packages("lme4",repos="http://r-forge.r-project.org"))
