Problems importing pysam on mac: Library not loaded: @rpath/libctabixproxies.cpython-39-darwin.so

[Endre Bakken Stovner]

I am having problems importing pysam in this file:

https://github.com/biocore-ntnu/epic2/blob/master/epic2/src/read_bam.pyx

Traceback (most recent call last):
File "/Users/jjp/opt/anaconda3/envs/epic2/bin/epic2", line 10, in
from epic2.main import _main
File "/Users/jjp/opt/anaconda3/envs/epic2/lib/python3.9/site-packages/epic2/main.py", line 5, in
from epic2.src.reads_to_bins import files_to_bin_counts
File "epic2/src/reads_to_bins.pyx", line 17, in init epic2.src.reads_to_bins
ImportError: dlopen(/Users/jjp/opt/anaconda3/envs/epic2/lib/python3.9/site-packages/epic2/src/read_bam.cpython-39-darwin.so, 2): Library not loaded: @rpath/libctabixproxies.cpython-39-darwin.so

I am not a C-wiz so any pointers to a solution would be appreciated :)
