Added automake as dependency for compiling on Mac


```

✱ make

glibtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'.
glibtoolize: linking file `m4/libtool.m4'
glibtoolize: linking file `m4/ltoptions.m4'
glibtoolize: linking file `m4/ltsugar.m4'
glibtoolize: linking file `m4/ltversion.m4'
glibtoolize: linking file `m4/lt~obsolete.m4'
+ aclocal -I m4
autogen.sh: line 44: aclocal: command not found
/bin/sh: ./configure: No such file or directory
make: *** [outside/libuv_0.11/Makefile] Error 127
```

Installed automake, and it compiled with 3 warnings, but other than that it works!
