However, I stumbled when I tried  to write an SConstruct file that searches for "C" and "Fortran" compilers in an order prescribed by me.  For example: assume that  I have "icc", "gcc" and "gcc-mp-4.6" on a mac (all paths to the executables are in the scons path, so no problem finding each of these 3 tools).

Hi Ludmil; this kind of thing is not easy to do with SCons today, but
we are thinking about how to make tool chain specifications more
flexible in a future version.
