This (hopefully) works now, after putting PySCIPOpt1.4.0.tar.gz into upstream, which can be found here:
*UPDATE* (from a later edit): now you need to put PySCIPOpt1.4.2.tar.gz https://pypi.python.org/packages/c0/b6/b619a33cd90dbf5579de341c873f85f0388030c47ee5da71a9113ee308d4/PySCIPOpt1.4.2.tar.gz#md5=4f175316bc3ba4ce97c284434a4b62f0
*UPDATE* (from yet a later edit): Check the description of the ticket for the latest version!
