To compile on Mac OSX with a component build, I had to add an explicit
dependency on src/base in this group.

  '<(DEPTH)/base/base.gyp:base',

Not sure why you did not need to.

Per comment over email, left this out.

                '../platform/blink_platform.gyp:blink_common',

As mentioned in review of ImageDecodeBench.cpp, we might be able to remove these
if we can define / use class WebPlatform as

  class WebPlatform : public blink:Platform

Could you try that?

Done.
