* Now requires much less dependencies.
 * Not all of the huge boost library is needed, only a tiny part, that is Boost.Thread and Boost.Datetime.
 * The dependencies are:
  * ffmpeg;
  * Boost.Thread and Datetime;
  * giflib;
  * libltdl or Development Haiku optional package;
 * And
  * optional packages which are already part of most Haiku builds: OpenSSL, Curl;
  * compile time only dependency of libagg.
 * Cannot use libagg 2.4 included in -lbe, require libagg 2.5. -lbe and -lagg order in linker command matters.
 * The ffmpeg media add-on could potentially be used instead of external ffmpeg package.
