MPB installation

Dear all,

I am trying to install MPB on my Mac and configure step is done  
successfully. When I execute the make command, I get the following  
error message:

fields.c: In function 'get_val':
fields.c:562: warning: unused parameter 'nx'
fields.c:562: warning: unused parameter 'last_dim_size'

fields.c:878: warning: unused parameter 'write_start0_special'
make[1]: *** [fields.o] Error 1
make: *** [all-recursive] Error 1

Does anyone has any suggestions?

Thanks in advance,

Alessandro
