Although not a NEMO issue per se, and most people would say that gadget2 is old software, I recently revived the install within NEMO, see $NEMO/usr/gadget and if you have the needed libraries, the command "mknemo gadget2" might then work for you.
The "make galaxy" benchmark can be run with different values of NP, and this resulted in snapshots that diverged, which is unexpected. NP=1 did however agree with a run outside of the runmpi environment.
