Unable to install fortran based packages in R - "gfortran -m32:not found"

I am writing an R package that has Fortran source code. In short, my problem is when I try to install the package I get the error "gfortran -m32: not found" however, I am able compile my code using gfortran -m32 when I'm not installing the package.

Detailed Version:

I have installed the newest version of R(3.1.1) along with the newest version of Rtools(31) and renamed my path variables accordingly (C:\Rtools\bin;C:\Rtools\gcc-4.6.3\bin;C:\Program Files\R\R-3.1.1\bin\x64;C:\msys;C:\Program Files (x86)\SSH Secure Shell;C:\Program Files\MiKTeX 2.9\miktex\bin).

For testing purposes, I downloaded the PropClust package from CRAN which has Fortran source code.

When I type "R CMD INSTALL PropClust_1.4.tar.gz" after building it, I get the following error:

* installing *source* package 'PropClust' ...
** libs

Although it says "gfortran -m32: not found" I have compiled my code in the same window with the same options(gfortran -m32 -O3 -mtne=core2 -c a.f90 -o a.out) with no problems. Has anyone had this problem before? I am running Windows 7 64-bit if that matters.

I had a similar problem : R was invoking gfortran-4.8 - an unrecognized command on my system - instead of gfortran. This problem was fixed upon creating the file ~/.R/Makevars within my home directory. Here are the contents of Makevars which points to the appropriate gfortran installation:

F77 = gfortran
FC = gfortran
FLIBS = -L/usr/local/gfortran/lib
