I found some help in the Readme.md file in the pdftotext package :
1) Install OS Dependencies :
on Debian, Ubuntu, and friends:
sudo apt-get update
sudo apt-get install build-essential libpoppler-cpp-dev pkg-config python-dev
on Fedora, Red Hat, and friends:
sudo yum install gcc-c++ pkgconfig poppler-cpp-devel python-devel redhat-rpm-config
2) Do the normal install :
pip install pdftotext
and it worked for me.
