Problems with Harlowe 3.0.0

[lpmwfx]

When I try to use the newest Harlowe story format on Twee2 I get the error below. It is Harlowe 3.0 I am trying to use downloaded from https://bitbucket.org/L/harlowe/overview Twee2 works fine with the building Harlowe 1.0.1 format, but as a newbie to Twee2, Twine and the whole IF concepts I wanted to have the latest versions to be sure it works.

You have to build the Harlowe project and move the compiled library into the twee2 story formats subfolder. Instructions are added at the bottom of the readme.
