Hi, this CL broke my linux build. I checked out skia alone, so there's no
libjpeg source code around...

Thanks!

Guanqun- We added an external dependency on libjpeg in
http://code.google.com/p/skia/source/detail?r=3334.  When you synced your client
past that revision, did nothing appear in third_party/externals/libjpeg ?

(In other words, the libjpeg source should have been added to your Skia tree
automatically for you...)

Ah, I figured why, because I'm not using svn directly, I'm using git svn. So git
svn doesn't help me pull these externals automatically... After checkout the
libjpeg under external directory, the compilation is OK now, sorry for the false
alarm.
