In other words, `make` is attempting to call `gfortran-4.8` to compile
FORTRAN code in your package, but is unable to find it -- likely
because it's not installed.
Since 'gfortran' is no longer distributed as part of Apple's command
line tools, you'll need to install it from another source -- Simon
Urbanek hosts a version of 'gfortran' at http://r.research.att.com/
(more specifically, in the `libs` directory at
http://r.research.att.com/libs/gfortran-4.8.2-darwin13.tar.bz2).
You'll want to unpack it in the root folder at `/` (or move it there
after unpacking); the directory structure is such that the necessary
pieces are dumped into `/usr/local/` and R will by default be able to
discover everything needed.
Alternatively (if you're prepared to do a bit more work), you can use
the OS X package manager homebrew to install 'gcc' and hence
'gfortran'. Install homebrew following the instructions here:
http://brew.sh/
and then, from the command line, call
brew install gcc
This will install an up-to-date version of both 'gcc' and 'gfortran'.
Since it won't be installed into a directory that's 'visible' to R by
default, you'll need to tell R how to find it -- you can check the
StackOverflow questions + responses here for ideas on how to
accomplish that.

As an aside -- I am not sure why make is attempting to call
`gfortran-4.8` rather than `gfortran`. You might have to check
`~/.R/Makevars` or other package configuration variables. (Do you
_really_ need to be compiling with `gfortran-4.8` specifically?)
