Sure, sounds reasonable! I'm unsure I'll have time to chase upstream
however. In the meantime, see the attached patch to get around the issue
with libid3tag.

I'm afraid I couldn't find a way to make the configure script work
without pkg-config. I got as far as patching it to think libid3tag was
found, but then I couldn't find how to set CFLAGS and LDFLAGS to include
libid3tag. It appears using pkg-config for some dependencies but not
others is tricky here.

So in the end, I settled with creating a temporary local .pc file. It
feels like a bit of a hack but I thought it would be the most
future-proof option, WDYT?
