A few days ago, gcc-4.3 became the default fortran compiler for the 
ports.  Go ahead and erase the gcc-4.2 compiler - create the gcc-4.3 
compiler, and everything after that will be fine.

If you don't want to increase kern.maxdsiz, then it looks like setting 
WITHOUT_JAVA will stop that error occurring.
