Configure build for ra.mines.edu.

--------------------------------------
Compiling on Mac OSX 10.6.x Snow Leopard
--------------------------------------
SILO:
./configure CC=gcc -arch x86_64 CXX=g++ -arch x86_64 F77=gfortran -arch x86_64 FC=gfortran -arch x86_64 r_arch=x86_64 --disable-silex

HYPRE
./configure CC=gcc -arch x86_64 CXX=g++ -arch x86_64 F77=gfortran -arch x86_64 FC=gfortran -arch x86_64 r_arch=x86_64 --prefix=/APPS/hypre-2.4.0b/

PARFLOW
./configure CC='gcc -arch x86_64' F77='gfortran -arch x86_64' FC='gfortran -arch x86_64' --prefix=$PARFLOW_DIR --with-clm --enable-timing --with-silo=$SILO_DIR --with-hypre=$HYPRE_DIR --with-amps=mpi1

make install
it goes fine all the way to the very end, then errors out w/
ld: duplicate symbol start in /usr/lib/crt1.o and /usr/lib/crt1.10.6.o
cd config
manually edit Makefile.config to change crt1.o in LDLIBS to 10.6.o
cd ..
make install, works fine

in pftools
same thing, errors out on same linking step/error duplicate libraries
in config, change Makefile.config to reflect crt1.10.5.o to 10.6.o this time in two places in the LDLIBS line
make install now almost seems to work, but odd messages at the end

then it errors out on dynlib

Manually add the -arch x86_64 to the end of the tools linking step to link as:

ld -dylib pftappinit.o printdatabox.o readdatabox.o databox.o error.o velocity.o head.o flux.o diff.o stats.o tools_io.o axpy.o getsubbox.o enlargebox.o load.o usergrid.o grid.o region.o file.o pftools.o top.o water_balance.o water_table.o sum.o -o ./bin/parflow.dylib -L/usr/lib -L/Users/reed/parflow/parflow.9-09/lib -lparflow -L/opt/local/silo/silo-4.7/lib -lsilo -ltcl -lc -arch x86_64

from the command line.  Then I can make again, it doesn't re-link but does install.
