openmpi-1.6.5 32 bits

[guicanella]

Ola galera, meu problema é: está dando um erro na instalação do meu openmpi-1.6.5 para 32 bits.

Minha maquina é 64 bits mas estou precisando intalar o openmpi 32 bits para rodar o programa firefly.
Antes de instalar o openmpi eu baixei os seguintes pacotes:

g++-4.6-multilib
g++-multilib
gcc-4.6-multilib
gcc-multilib
gfortran-4.6-multilib
gfortran-multilib

Eu so o ubuntu 13.04. Eu faço exatamente esses comandos aqui:

$ tar xvfj openmpi-1.4.5.tar.bz2

$ cd openmpi-1.4.5

$ ./configure --prefix=/opt/soft/openmpi-1.4.5 CFLAGS=-m32 CXXFLAGS=-m32 FFLAGS=-
m32 FCFLAGS=-m32

$ make

$ sudo make install

Mas quando eu uso o comando "make" aparece esse erro:

/usr/bin/ld: i386:x86-64 architecture of input file `asm/.libs/libasm.a(atomic-asm.o)' is incompatible with i386 output
