That is strange - did you use --with-blas='-framework vecLib' --with- lapack ? If so, please send me your config.log. As of R-devel that is the default now, but for R 2.1.1 you need to specify it. You may also want to add F77=g77 if you have both gfortran and g77 around just to make sure. > However, I remember seeing an email here that said use the 3.4.x > compilers unless you have a good reason not to (and the good reason > was wanting a 64 bit build which I don't). Is this still the > prevailing wisdom? Yes, there are still problems with 4.x - mainly with gfortran (it still segfaults on simple Fortran code and is slower than g77). We have worked around some of the show-stoppers in R-devel, but it's still not recommended. > I want a safe, stable, useable build.
