Then you will have to figure out why, when you run the configure script, it
shows gfortran runs when it invokes "ifort --version". It's something in your 
environment or the way in which you run the configure script.

You could probably debug the problem by just creating a little shell script
that runs "ifort --version", and trying to run it under the same conditions you 
use to run configure. For example, if you run configure using sudo or as root
(not recommended because some environment variables aren't inherited by
root subshells), then run this little shell script the same way, and see if it 
fails 
the same way. Then find and fix the cause of the problem, which may be a 
problem with your PATH, with the shell you are using, with a shell alias, with
symbolic link, or something else.

Altrernatively, you can set FC and F77 to the absolute path for ifort before 
invoking configure and see if that works. We can't reproduce the problem
here, so would still be interested if you discover the cause and let us know.

Thanks.
