Hmm. Looks over-complicated to me. What works for me on AMD64 is to
have a config.site file in my BUILD-GOTO directory, containing

> cat config.site
BLAS_LIBS="-L/home/pd/GOTO -lgoto_opt64p-r0.96 -lpthread"
CFLAGS="-O3 -g"
#CFLAGS="-g"
FFLAGS=$CFLAGS
CXXFLAGS=$CFLAGS

(the .*FLAGS business is optional, of course). With this in place, a
simple ../R/configure followed by make seems to do the trick.

I'll give it a try on my FC3 system, but it's a 500 MHz PIII, so it
takes a while...
