It seems that the MA library expects a different size of integer than what it is given. As the code normally compiles with 64-bit integers you will have to manually specify that it should use 32-bit integers. To do this do:

   export USE_64TO32=yes

and replace the compilation commands with

   make realclean
make nwchem_config NWCHEM_MODULES=all
make 64_to_32
make

with these settings and commands the code should compile correctly.
