[Mac OS X] LIBLINEAR library not found

After performing the setup steps described in README.md, I am not able to run the proposed example for polarity detection.

Context

Operating System: MacOS Big Sur (v11.2.3)

Process

The git lfs and java 8+ requirements were already satisfied on my machine. Therefore, I only had to perform the following steps to complete the setup:

Install a Python 3.7 virtual environment
```
python3.7 -m venv env
```
Install the dependencies declared in requirements.txt
```
pip install -r requirements.txt
```

Finally, I issued the example command:

sh classification.sh -i Sample.csv -d sc

Expected result

I expect to get a .csv file containing the sentiment predictions for the sentences in Sample.csv.

Current result

At first, the script appears to be running smoothly, producing the following output:

Then, it raises the following exception:

During handling of the above exception, another exception occurred:
