If you have ifort 9.1 on path when you run the phenix "install" command
your build will be as efficient as the one we make.
Newer ifort versions are not supported due to difficulties linking
with the C++ runtime (the latest CCP4 libs used by solve/resolve
employ the mmdb C++ code even if used from Fortran).
The "install" command doesn't support Intel C++ (although it is
supported by the lower-level build system; for C++ the runtime
differences are small).
