gfortran and pgf90

I am new to linux. Recently I try to install a bioinformatics program called I-SITES and I have been having a lot of problem compiling it.

It seems like it needs pgf90, which i think is fortran 90. However, my machine only has gfortran which i think is a fortran 95. I dunno why I have been having problem compiling this. I can' t tryto install pgf90 though coz i don't have the administrator password. and I'm not so sure even that would be the best solution either.

Anyway, i think there are some commands in pgf90 that gfortran does not support

the Makefile starts with:
FLAGS = -Mextend -Mbackslash -Bstatic -fast

but gfortran does not understand -Mextend, -Mbackslash, and -fast

then i converted -Mextend to -ffixed-line-length-132 which i think probably did the job of replacing it in gfortran. But I can't get the same replacement for -Mbackslash and -fast

the error I get when i try to compile it is :

gfortran: unrecognized option '-Mbackslash'
f951: error: unrecognized command line option '"-fast"
make: *** [isflags.o] Error 1

can anyone help me with this?

You are right in this. pgf90 is part of the commercial Portland Group compiler suite (I believe the suite also has an f95, the f90 version is for compatability). I think you can get a short term-demo copy of it which may solve your current problem, or you could try removing the error-generating options for the GNU fortran compiler.
