How did you build/get freetype.dll? If it was built using Visual Studio,
freetype.dll might have been linked against a newer C++ runtime such as
msvcr71.dll that is not shipped with windows by default. You clearly
need to deploy C++ runtime libs as well with your product.
You may benefit from such tool as a dependency walker
On linux you can just use ldd.
Hope this helps,
