[SOLVED] Building libtorrent with ponce slackbuild script fails with python binding version error (PEP 440)

Hi, I'm on slackware64-current and I've tried to compile the version 1.2.19 of libtorrent-rasterbar, which is the current intended version for the ponce script I'm using, but it gives an error of versioning while compiling the python bindings I can't understand:
