Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.


Relevant part (hopefully):
> make[1]: Entering directory '/<<PKGBUILDDIR>>'
> dh_auto_build
> cd build && ./build.py full.cfg OpenLayers.js
> No jsmin
> No closure_ws
> No minimize
> Merging libraries.
> Importing: OpenLayers/StyleMap.js
> Traceback (most recent call last):
>   File "/<<PKGBUILDDIR>>/build/./build.py", line 163, in <module>
>     build(args[0], args[1], options=options)
>   File "/<<PKGBUILDDIR>>/build/./build.py", line 65, in build
>     merged = mergejs.run(sourceDirectory, None, configFilename)
>              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
