Cannot invoke inklecate from PATH on OSX

While looking at https://github.com/inkle/inky/issues/104, I needed to invoke inklecate from the command line. I'd gotten somewhat used to having it on my PATH. When I upgraded to the latest version, this no longer worked.

Output of inklecate as if by `./inklecate`:
```
Usage: inklecate2
-o : Output file name
-c: Count all visits to knots, stitches and weave points, not
just those referenced by TURNS_SINCE and read counts.
-p: Play mode
-v: Verbose mode - print compilation timings
-x : Use external plugin. 'ChoiceListPlugin' is only available plugin right now.
-t: Test mode - loads up test.ink
-s: Stress test mode - generates test content and
times compilation
-k: Keep inklecate running in play mode even after story is complete
```
Output of inklecate by `inklecate`:
```
Usage is: mono [options] program [program-options]

Development:
--aot[=] Compiles the assembly to native code
--debug[=] Enable debugging support, use --help-debug for details
--debugger-agent=options Enable the debugger agent
--profile[=profiler] Runs in profiling mode with the specified profiler module
--trace[=EXPR] Enable tracing, use --help-trace for details
--jitmap Output a jit method map to /tmp/perf-PID.map
--help-devel Shows more options available to developers

Runtime:
--config FILE Loads FILE as the Mono config
--verbose, -v Increases the verbosity level
--help, -h Show usage information
--version, -V Show version information
--runtime=VERSION Use the VERSION runtime, instead of autodetecting
--optimize=OPT Turns on or off a specific optimization
Use --list-opt to get a list of optimizations
--security[=mode] Turns on the unsupported security manager (off by default)
mode is one of cas, core-clr, verifiable or validil
--attach=OPTIONS Pass OPTIONS to the attach agent in the runtime.
Currently the only supported option is 'disable'.
--llvm, --nollvm Controls whenever the runtime uses LLVM to compile code.
--gc=[sgen,boehm] Select SGen or Boehm GC (runs mono or mono-sgen)
--arch=[32,64] Select architecture (runs mono32 or mono64)
