problem compling with reax

Dear Lammps maillist,
I'm trying to compile lammps (9Dec-11) with the reax libraries on my Dell Intel Xeon running CentOS 6.
During compilation there are warnings like:
read_data.cpp:990: warning: deprected conversion from string constant to 'char*'

I get an executable lmp_serial, but when trying to run the CHO or RDX example I get the error message:
ERROR: Invalid pair style (force.cpp168)

The executable runs on non-reax problems.

When buildning the reax library, I edited Makefile.lammps and Makefile.lammps.gfortran:
reax_SYSINC =
reax_SYSLIB = -lgfortran
reax_SYSPATH = -L/usr/lib/gcc/x86_64-redhat-linux/4.4.4

I ran:
make -f Makefile.gfortran
and got the libreax.a without complaints.

I would be very thankful for any input on this problem!

Getting libreax.a is the first step. Did you
also include the reax pacakge in your LAMMPS
build? E.g.

make yes-reax
make g++

If not, you will get the error you listed.
The doc pages on packages explain all
of this.
