I could not get those to run with method="libcurl", possibly since I have not
yet updated to 3.2.2? This did run:
checkfun <- function(ver) {
uu <- paste0(urlhead,ver, urltail)
rr <- readLines(url(uu))
any(grepl("could not find function.*REMLcrit",rr))
}
sapply(versions,checkfun)
devel-osx-x86_64-clang release-osx-x86_64-mavericks
FALSE FALSE
release-osx-x86_64-snowleopard

[R.app GUI 1.66 (6956) x86_64-apple-darwin10.8.0]
I installed today an updated macbinary version of lme4, lme4_1.1-8.tgz, which
the GUI package installer did for me with all the many dependencies. That is
the latest version at CRAN for SL:
http://cran.cnr.berkeley.edu/bin/macosx/contrib/3.2/
Is that version "out of date"? I suppose it might be, since I see this at the
top of the CRAN package check:
• using R version 3.2.0 Patched (2015-04-28 r68272)
• using platform: x86_64-apple-darwin10.8.0 (64-bit)
• using session charset: UTF-8
• checking for file ‘gamm4/DESCRIPTION’ ... OK
• this is package ‘gamm4’ version ‘0.2-3’
I get this at the console:

I'd be happy to remove and attempt reinstalling from source something else if
that would be of any use to you wiser folk, who know what you are looking for
and only need cannon fodder, er, willing test subjects.
