Can't install pyicu in my mac. Error: library not found for -licule

Created by: miguelwon

Hi, So I'm having some troubles installing pyicu in my mac. I'm running the following command:

CFLAGS='-I/usr/local/opt/icu4c/include -I/opt/local/include' LDFLAGS=-L/usr/local/opt/icu4c/lib pip install pyicu

and it results in the error:

ld: library not found for -licule

Which library is this licule?
