Ld Library Not Found For Root Mac

Hi all,
this problem is probably more related with mono than Xamarin but generaly I need to know how to use a .NET dll onto Xamarin using Mono on OS X.
I've done the documentation research, but the problem is to complex to me to fill the gaps and understand what to do.

What?
I'm trying to use LibUsbDotNet with in C# program.

I'm using:
OS X; Xamarin; Mono; C#; LibUsbDotNet

Problem:
I've run LibUsbDotNet examples on Xamarin but have this problem:
'libusb-1.0 library not found. This is often an indication that libusb-1.0 was installed to '/usr/local/lib' and mono.net is not looking for it there. To resolve this, add the path '/usr/local/lib' to '/etc/ld.so.conf' and run 'ldconfig' as root. (http://www.mono-project.com/DllNotFoundException)'

What I know:
$ ls -la /usr/local/lib

Jan 28, 2016 ld: library not found for -lbundle1.o. The code complied but the bundle library was missing during linking, this code worked last time I did it, so the suspect was the new OS X El Capitain. More specifically the suspect was the Xcode library, so I reinstalled the developer tools using the command: xcode-select –install.

What I don't know:
The documentation tells how to solve on Linux'...add the path '/usr/local/lib' to '/etc/ld.so.conf' and run 'ldconfig' as root....'
but I don't know how to do it on OS X...
