Disable 'Crippled Lapack' warning in RcppArmadillo - r

Question

I'm using RcppArmadillo to solve a linear system. The R binary for Macs from CRAN is configured to use a built-in subset of BLAS and Lapack, and I have not been successful in building R to use an external BLAS + Lapack (I sent an email to r-sig-mac for help, but so far haven't received any answer).
Unfortunately, in addition to a possible lack in performance, every time I run the code I'm greeted with a low-level warning,
warning: solve(): refinement and/or equilibration not done due to crippled LAPACK
which quickly fills my terminal console (I'm running this in a loop). How can I configure RcppArmadillo to not issue this warning?

Look at configure when you install it; check the test output. The code (minus some comments) essentially is:
## external LAPACK has the required function
lapack=$(${R_HOME}/bin/R CMD config LAPACK_LIBS)
hasRlapack=$(echo ${lapack} | grep lRlapack)
if [ "${hasRlapack}" == "" ]; then
## We are using a full Lapack and can use zgesdd -- so #undef remains
echo "system LAPACK found"
cp inst/include/RcppArmadilloLapack.h.in inst/include/RcppArmadilloLapack.h
else
## We are using a R's subset of Lapack and CANNOT use zgesdd etc, so we mark it
echo "R-supplied partial LAPACK found"
echo "* some operations may not be available"
sed -e 's/\/\/ \#undef ARMA_CRIPPLED_LAPACK/\#define ARMA_CRIPPLED_LAPACK 1/' \
inst/include/RcppArmadilloLapack.h.in > inst/include/RcppArmadilloLapack.h
fi
So in a nutshell you have two options:
i) have a real external LAPACK or
ii) use an R version that has a non-crippled LAPACK bundled -- ie R 3.3.0.
Edit on 12-Mar-2016: So there was a bug in that R 3.3.0 was not recognized properly in the case of not having a system LAPACK -- ie OS X as poor Windoze is handled differently anyway. This is now taken care of in the GH repo. Thanks to #baptiste for spotting it.
