But why not all needed packages?

The dependencies have been updated.

This packages are requred for building, please add to pkgbuild:
gtk2
libice
libsm
desktop-file-utils

Good suggestion. I changed it.

I would recommend passing '--sysconfdir=/etc' to ./configure so that userhelper will read under /etc/security/console.apps/ instead.
