ffmpeg: ld-elf.so.1: /usr/local/lib/libtasn1.so.6: Undefined symbol "strverscmp@FBSD_1.7"

Currently my Emby plugin is failing with this error because ffmpeg is broken. I saw another thread that seemed to indicate that libtasn1 4.18 might be a viable workaround, but I have no idea how to "downgrade" a package once it's been upgraded.
