Post portaudio instructions on the Pi

make_install.out

----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
/usr/bin/install -c -d /usr/local/include
for include in portaudio.h; do \
	/usr/bin/install -c -m 644 -m 644 ./include/$include /usr/local/include/$include; \
done
/usr/bin/install -c -d /usr/local/lib/pkgconfig
/usr/bin/install -c -m 644 portaudio-2.0.pc /usr/local/lib/pkgconfig/portaudio-2.0.pc

------------------------------------------------------------
PortAudio was successfully installed.

On some systems (e.g. Linux) you should run 'ldconfig' now
to make the shared object available.  You may also need to
modify your LD_LIBRARY_PATH environment variable to include
the directory /usr/local/lib
