ok, rinse and repeat...

I retried with various compilation and linking options and firstly it 
appears that if I link to the static library everything works fine. 
However if I have FFLAGS of "-fPIC -O2" and link arpack with

g++ -shared -Wl,-soname -Wl,libarpack.so -o libarpack.so  SRC/*.o 
UTIL/*.o -llapack -lblas

as I would have thought was necessary, I have problems.. In fact I can't 
seem to find any shared library version that I build that does work....
