Out of curiosity, did you check the skia dir out manually? I don't seem to have
one in my checkout? Do we need to add skia to DEPS?

I am doing the build inside a Chromium tree for now. I couldn't figure out a way
to easily do it in a standalone PDFium tree.

To test, I use:
GYP_DEFINES="pdf_use_skia=1" ./build/gyp_chromium -Dcomponent=shared_library
ninja -C out/Debug pdfium_test 
./out/Debug/pdfium_test --png /some/local/pdf/file

An aside: I have the new/delete mismatch with non-shared library builds as well.
