Yes, you're right.
I'm compiling CUDA using a 4.4 C/C++ compiler but a 4.6 fortran compiler.
But is this the reason?

Does anyone know how to change the fortran compiler to a 4.4 compiler?
For some reason changing the gcc version changes the C/C++ compilers but not the Fortran compilers.

Sounds like you don't have version 4.4.6 of gfortran installed (or installed
correctly).  You need to have equivlaent releases of gcc and gfortran (and
g++) available.

What does "gfortran -v" return?  (Not sure why the configure script is not
printing this out....)
