"multimedia/ffmpeg" and "multimedia/ffmpeg010" both include
"".  This can (and has) confused applications that need
the older "ffmpeg010" package, but also have "ffmpeg" (v1.0.1) installed.

When such an application asks for "", the linker finds
it in "/usr/pkg/lib/ffmpeg010/".  When subsequently
asked for "", the linker finds it in
"/usr/pkg/lib/".  The application fails, likely with
much complaining about inability to find codecs and spewing messages
with bizarre numbers which appear to represent addresses or offsets.

On a system with pkgsrc-2012Q4 and an up-to-date "pkgsrc-wip",
install "wip/electricsheep-svn" (bringing in "multimedia/ffmpeg010" as
a dependency).

Then install "multimedia/ffmpeg" (or a package which depends on it).

Attempt to run 'electricsheep'.

Watch fireworks.

Also "ktruss -i electricsheep" and watch the shared libraries being
Is there a way to force linking against the full library version?
"ffmpeg010" has "" while "ffmpeg" has version

Alternatively, pull up ffmpeg (v1.1.x) from HEAD as it has
"" which will eliminate the collision at the major version

There may yet be a problem as,, and still collide between the two versions of ffmpeg.
