When compiling media-libs/mlt with the rtaudio USE flag set, the rtaudio module tries to pull in the pulseaudio headers. If pulseaudio is not installed, this fails. The ebuild probably needs to specify pulseaudio as a dependency when the rtaudio USE flag is set.

Adding the pulseaudio USE flag to media-plugins/alsa-plugins and (re-)compiling that first brought in pulseaudio (sigh) and allowed the media-libs/mlt build to finish.
It looks like this is only happening with the bundled rtaudio. Could you try merging media-libs/rtaudio then rebuilding mlt? (it should pick it up automatically)
Yes, you're correct. I removed the pulseaudio USE flag dependency and did a depclean to flush pulseaudio, and re-confirmed mlt-6.2.0-r1 wouldn't compile. I then emerged media-libs/rtaudio-4.0.12-r1 and recompiled mlt; this time it compiled without problems, and without pulseaudio on the system.
Thanks for testing. This is now fixed in git. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=4403c3564ef747e8207426c8d8fc7951abe72a58
