Cannot install mon on FreeBSD 9.1

[snowindy]

I tried to install mon on FreeBSD 9.1 and I get this. What's wrong?

    root@eugene:/tmp/mon/mon-master # make install
    cc -D_GNU_SOURCE -std=c99 -I deps/ -c src/mon.c
    In file included from src/mon.c:21:
    deps/ms.h:34:7: warning: no newline at end of file
    cc -D_GNU_SOURCE -std=c99 -I deps/ -c deps/ms.c
    In file included from deps/ms.c:11:
    deps/ms.h:34:7: warning: no newline at end of file
    cc -D_GNU_SOURCE -std=c99 -I deps/ -c deps/commander.c
    cc  -o mon
    cc: No input files specified
    *** [mon] Error code 1

    Stop in /tmp/mon/mon-master.

hmm looks like maybe the make wildcard thing is failing
