More investigation revealed that for some reason my python doesn't import satellites_swig, which is where ao40_syncframe_soft is located

Traceback (most recent call last):

Turns out that python errors is unhelpful, as more investigations revealed that _satellites_swig cannot be imported as it cannot find libfec.so, which is because it is located in /usr/local while Arch Linux expects everything to be in /usr, so now after recompiling libfec with ./configure --prefix=/usr fixed everything
