You are correct in stating that the downloadable binaries that were
built with gcc 3.x would have used g77 as the Fortran compiler where
necessary. Binaries that were built with gcc 4.x would have used
gfortran. Our Linux build hosts are all using gcc 4.x/gfortran, I
believe.

I'll assume that, when you reference 'the documentation' that you
mean this document:

        http://www.ncl.ucar.edu/Download/build_from_src.shtml

Assuming that, it sounds as though you're having trouble at this
point in the document:

        Customize NCL build environment (http://www.ncl.ucar.edu/Download/
build_from_src.shtml#CustomizeNCLBuildEnvironment)

The instructions there build the executable 'ymake-filter' (that's
what the 'make -f Makefile.ini' command does) -- did you do this step?
As you're trying to build on a Linux host, I suggest that you have a
look at the various files named 'LINUX.<something>' to see which best
meets your needs. These files are there as templates for various
system configurations; the idea is to choose one which most closely
meets your needs, rename it 'LINUX' and edit to suit. Do this prior
to the steps noted above (i.e. before you 'make / ymake').

Please let us know if you have more questions.
