OSError: Could not load shared object file: libllvmlite.so

Description

I was trying to install libora on a aarch64 machine by following the docs:

$ sudo apt install python3-dev
$ pip3 install Cython --user
$ wget https://github.com/librosa/librosa/archive/0.7.2.tar.gz
$ tar -xvf 0.7.2.tar.gz librosa-0.7.2/
$ cd librosa-0.7.2/
$ python3 setup.py install

Ran into outdated TBB error:

numba/np/ufunc/tbbpool.cpp:89:108: error: no matching function for call to ‘tbb::internal::task_scheduler_observer_v3::task_scheduler_observer_v3(tbb::interface7::task_arena&)’
fix_tls_observer(tbb::task_arena &arena, int mask) : tbb::task_scheduler_observer(arena), mask_val(mask)

So I began building TBB from source (also had to build cmake because linux amirite):

$ sudo apt install libffi-dev
$ git clone https://github.com/wjakob/tbb.git
$ mkdir build && cd build
$ cmake ..
$ make
$ sudo make install

Back to librosa, finally got everything to compile:

$ sudo python3 setup.py install

but when I try to use the library, it said that I’m missing a share object from libllvmlite.so:

python3 -c 'print(__import__("librosa").__path__)'

OSError: Could not load shared object file: libllvmlite.so

llvmlite seems to be installed:

$ python3 -c 'print(__import__("llvmlite").__path__)'
['/usr/local/lib/python3.7/dist-packages/llvmlite-0.32.1-py3.7.egg/llvmlite']

Although I can’t find any .so file, I would really appreciate the help if you can point me to the right direction.
