building tp_smapi from AUR

[Fons Adriaensen <fons@xxxxxxxxxxxxxx>]

Don't know if this is the right place to ask...

I'm trying to install tp_smapi from AUR. The maintainer is
listed as 'xduugu' without mail address.

Everything runs fine until:

And indeed there's no hdaps.ko in the 'extra' directory.

Any ideas ?

TIA,
