I just did a fresh install after drive formatting of OS X 10.10.5 on my
MacBook Air.  After Installing the latest Csound for OS X, I was getting
warnings about libvirtual.dylib and libwidgets.dylib not loading.
Also, csound -z did not list the FL* opcodes.  Upon checking with otools -L
and ls I found that both were referencing libpng in /usr/local/lib.
But, it was not there.  Since this was a fresh install,
previous versions of OS X csound that put it there had never been installed.
Upon copying libpng from the framework, the warnings went away, csound -z
listed the FL* opcodes and the virtual keyboard worked.

Perhaps there has been an incomplete change of library locations.

Note - this was using the current June 8 version of the .dmg file.
