fortran

[Gustavo López]

Dear Sirs or Ladies,

I have a Power Mac G4 with operating systems Mac OS X 10.4.5 and want  
to install
FORTRAN compiler to make research. I found your email address at  
www.gnu.org/software/gcc/fortran, but I have not idea where I can get  
this compiler (free)
and how to make its installation.  Could you help me with all of  
this, please ? Thanks
before hands,

Sincerely,  Gustavo López
