Compilation errors using qt 4.8.5

I have followed the directions at http://ift.tt/1tpXSOV for installation on Windows 7. I have uninstalled Qt and reinstalled and tried to do this many times, and I can't get it to work.

I added to qamke.conf the line

QMAKE_LFLAGS = -static-libgcc -static-libstdc++

The other line in the directions for QMAKE_RCC was already there.

When I do this command in the directions...

C:\development\Ruby193\capybara-webkit>bundle exec rake build

I get errors - starting with:
