Missing dependency on portaudio dev files

[brackleian]

Portaudio was installed by cargo while building RustAudio synth. It produced a linker error, which I traced back to portaudio. Building portaudio requires the Ubuntu package portaudio19-dev to be installed first.

OS is Ubuntu-derived 16.04LTS.

I'm new to Rust and Cargo, and not aware of how cargo resolves or detects these dependencies, or if it is able to. If possible, a more comprehensible explanation of the error would be nice, rather than about 80 'undefined reference' messages. Better still, suggest (or even install) the package! :)
