Thanks for the links.

I've got GraphicsMagick version 1.3.12 built from source. I'm using 
Mandriva Free 2008.1 (spring edition) with a number of linear algebra libs 
from Mandriva. Arpack and GraphicsMagick weren't available from Mandriva 
so I found source. Arpack96 from the original author
ftp://ftp.caam.rice.edu/pub/software/ARPACK/
doesn't work as it doesn't have a required function. I found another site 
with a link to a German site (Andreas Kloeckner?) that has an updated 
source tarball for "auto" build tools.

Finding a new enough arpack is a difficulty for those trying to build from 
source.

My gcc , g++ etc is version 4.3.4 built from source with default 
configuration. One of the first Fortran compilers configure looks for is 
g77, and the typical way for gfortran to be installed is to include links 
to it named g77, g95 and f95. Some Fortran source code doesn't even know 
about gfortran. I've found source on netlib dating back to about 1970.
