Setting up TURN server; "dyld: Library not loaded, Reason: image not found"

Question

I am trying to set up a TURN server with Coturn, in accordance with these instructions, but I am getting stuck at this step:

Add the long-term TURN users with the turnadmin utility. For example, this command adds user ninefinger with password youhavetoberealistic, realm north.gov, to the default sqlite database:

$ sudo turnadmin -a -u ninefingers -r north.gov -p youhavetoberealistic

Add the admin user(s) to the database, with turnadmin utility. If you added those users, then will be able to connect to the TURN server ports over HTTPS from your browser and perform admin tasks with the web interface.

For example, this command adds the admin user bayaz with password magi:

$ sudo bin/turnadmin -A -u bayaz -p magi

In my turnserver-4.5.0.8 directory, I enter sudo turnadmin -a -u <some_username> -r -p <some_password> (not entering a value for -r gives it the default realm, correct?), and I am given the following error message:

dyld: Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib Referenced from: /usr/local/lib/libevent_openssl-2.0.5.dylib Reason: image not found

I have tried adapting answers from this question to my case, but I do not know what the @executable_path is, which means I also don't know which libraries I should be using install_name_tool -change on and in what order. (My confusion here likely stems either from my not fully understanding how turnadmin is trying to go about its business, or from my having no clue what /usr/local/opt/openssl/lib/libssl.1.0.0.dylib and /usr/local/lib/libevent_openssl-2.0.5.dylib actually are and how they differ from one another.)

Incidentally, the second answer to the above-linked question says:

In the target's General tab, there is an Embedded Binaries field.

add required framework and crash is resolved.

Is this applicable to my case? I do not understand the terms "target" and "framework" (again, this probably has to do with my not understanding what /usr/local/opt/openssl/lib/libssl.1.0.0.dylib and /usr/local/lib/libevent_openssl-2.0.5.dylib are.)

I also tried upgrade brew, but this didn't change anything for me.

I'm running Max OS X.

Edit: May be worth noting that my attempt to set up Coturn is born of step 3 in the webrtc Deployment instructions here.

Edit 2 (regarding the linked question above): What is the difference between @executable_path/libboost_something.dylib and the value that would be entered as as substitute for the "exefile" example variable?
