Comment (by eborisch):

 Note the first line of the output:

 **Error: Command line argument is needed!
 **

 Try compiling something with it. Or even just `mpicxx -show`:
 {{{
 $ mpicxx
 Error: Command line argument is needed!
 This script (/opt/local/bin/mpicxx) is being called recursively, check
 that MPICH_CXX does not refer to mpicxx.

 $ mpicxx -show
 /usr/bin/clang++
 -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX13.sdk
 -I/opt/local/include/mpich-mp -L/opt/local/lib/mpich-mp -lmpicxx -lmpi
 -lpmpi
 }}}
