I can compile it just fine, install base-devel and meson
There's also another program, songrec in the regular repos not just in AUR
base-devel is already installed while meson is installed by trizen.
I added an option that removes installed dependencies so after is removed.
I installed meson manually before and I have the same error.
I installed songrec from arch/community.
It builds OK here, although the first try building in /tmp in RAM it ran out of disk space, it must use a lot in the build. The mention of "module" in the error sounds like there could be some python module involved? Perhaps try updating with Syu, and check if you have any related AUR packages using Python that need a rebuild as there has been a big version update for Python in the last 24hrs.
After updating it worked.
