This doesn't look right.  I'm not sure what it is about.  It may cause
trouble later, but it is not the cause of the problem below.

This usually indicates you are mixing compiler versions, and the 3.4.6
in the -L lines above would suggest that.  I assume these -L options
are coming from the $(FLIBS) variable, which are the Fortran libraries
the configure script found by asking the Fortran compiler you are
using which libraries it needs.  My guess is that you are mixing nan
obsolete version of g77 with a more recent gcc/g++.  If so, make sure
you have gfortran installed and that it is the same version as your
gcc and g++ compilers and add

  F77=gfortran

to the configure command line to use gfortran instead of g77.
