Portable Real-Time Audio Library

PortAudio is a portable audio I/O library designed for cross-platform support
of audio. It uses a callback mechanism to request audio processing. Audio can
be generated in various formats, including 32 bit floating point, and will be
converted to the native format internally.

This package renames portaudio.so* to portaudio18.so* So both versions, the
actual portaudio-v19 and v18 can coexist.
