Don't worry about clicking on it. What happens when you run 'file 
/opt/intel/lib/ia32/libifport.so.5'? The reason I'm asking is because 
the following error:

seems to indicate that the dynamic linker cannot find libifport.so.5. One 
way this can happen is if it's in directory that's not on a 
LD_LIBRARY_PATH. Can you check that it is? Try 'ldd 
/home/john/LREWI15_TIO/./swat2009_i64_calibrate.so'. Make sure that 
there is a line in there that looks something like (I'm guessing):

  libifport.so.5 => /opt/intel/lib/ia32/libifport.so.5 (...)

Also, do you have other programs on that system that you compiled with 
Intel's Fortran compiler that work correctly?

And let me echo Dirk's suggestion to familiarize yourself with R 
packages -- what happens when you load a package, and how the package 
mechanism interacts with compilation and linking of dynamic libraries. 
To try otherwise will only cause you a lot of frustration, as you've 
probably already discovered.
