Similar solution to your 3th step, if gsl was installed to different location, is to run R with flags and install gsl. Perhaps this helps you build gsl package without touching source.

CFLAGS="-I/usr/local/opt/gsl/include" LDFLAGS="-L/usr/local/opt/gsl/lib -lgsl -lgslcblas" R
...
> install.packages("gsl”)
