The fact that you post in HTML and make no effort to describe your setup makes me suspect you may also have missed the instructions about installing XCode and configuring R for compiling source packages. This can still be done with the binary distribution versions of R and R.app, and do not require that you build R from sources. See the CRAN-Mac-tools page:

https://cran.r-project.org/bin/macosx/tools/

It used to be the case that one needed Xcode and Command Line Tools installed. (I do have them.) I cannot tell from the current Mac-devel page whether that is still the case. I have a current version of R running in El Capitan. This is my ~/.R/Makevars file:

# created by rstan at Thu Mar 19 11:26:15 2015 
CXXFLAGS = -mtune=core2 -O3 $(LTO)  #set_by_rstan
R_XTRA_CPPFLAGS =  -I$(R_INCLUDE_DIR)   #set_by_rstan
CC=/usr/local/clang4/bin/clang
CXX=/usr/local/clang4/bin/clang++
LDFLAGS=-L/usr/local/clang4/libI 

I just executed the following commands in the R.app environment.

source("https://bioconductor.org/biocLite.R")
biocLite()
# declined the offer to update packages
 biocLite(c("ChemmineR"), type="source", dependencies=TRUE)

It then tried to install all the dependencies (failing for ChemmineOB because the OpenBabel system requirement was not met) and got a  report of success with ChemmineR and the package was capable of loading. So I've successfully tested my theory that the only barriers to successful compilation of ChemmineR from source are lack of knowledge of the R and Bioconductor ecosystem (and lack of one external package.) I'm not that interested in getting a full package installed, so haven't taken the time to install OpenBabel and recompile ChemmineOB.


Hope this helps;
David.
