> FC gyre_ad.f90 > dyld: Library not loaded: /Applications/mesasdk/lib/libmpc.3.dylib mesasdk was not installed in the default location (/Applications/mesasdk). When we set DYLD_LIBRARY_PATH to $MESASDK_ROOT/lib it worked fine. Perhaps it's a good idea to also set this variable in mesasdk_init. Cheers, Bram
