http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46445 --- Comment #2 from kargl at gcc dot gnu.org 2010-11-12 00:07:59 UTC --- This isn't a gfortran problem. You need to either install an older version of gfortran that has libgfortran.so.1 or rebuild your application with the version of gfortran that you have.
