Is their objection to gcc or compilers at all? Sun's own Studio 11 compilers are now free (and at least as good as gcc in that environment). > My question: After a successful build, is there anytime that R might > call the compiler?

The latter is run by R CMD INSTALL and that is run by install.packages() and elsewhere. But you would need to have specified some C/C++/Fortran source code, so would be expecting this. -- Brian D.
