Hmm... I installed DR17 succesfully from Slackbuilds a while ago... Make sure you got the build order right, build evas before
From the enlightment package README:
This requires embryo, edje, e_dbus, efreet, and eeze.
The complete build order is: eina, embryo, eet, evas, ecore, edje,
e_dbus, efreet, eeze, enlightenment.
