I attempted to install on my laptop today:

Not sure why it had issues with gfortran. However, I am running 4.9 not 4.8? WIll try downloading and making localy, outside of R.

This is because, for whatever reason, R defaults to an old version of
gfortran. The way to fix this is to set the Fortran version in the
~/.R.Makevars file.

From "R Installation and Administration" (
http://cran.r-project.org/doc/manuals/r-devel/R-admin.html):

"The default compilers specified in
/Library/Frameworks/R.framework/Resources/etc/Makeconf depend on the
version of OS X under which R was installed, and are appropriate to the
latest version of the command-line tools for that version of OS X. The
settings can be changed, either by editing that file or in a file such as
~/.R/Makevars (see the next section). Entries which may need to be changed
include ‘CC’, ‘CXX’, ‘FC’, ‘F77’, ‘FLIBS’ and the corresponding flags, and
perhaps ‘CXXCPP’, ‘DYLIB_LD’, ‘MAIN_LD’, ‘SHLIB_CXXLD’, ‘SHLIB_FCLD’ and ‘
SHLIB_LD’.

So for example you could select clang for both C and C++ with extensive
checking by having in ~/.R/Makevars

CC=clang
CXX=clang++
CFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
CXXFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion

and for a version of gfortran-4.2 we needed

FLIBS=-lgfortran"

Let me know if that works!

Trying this now, thanks!

Fixed. Had to add this to my .R/Makevars file in my home:

FC=gfortran

Now finds my "custom" install of gfortran 4.9.2 and makes/builds/installs OK

Glad it worked! I also added the fix to the README.md. It probably makes more sense to put it there since it's the first thing people see before installing.
