libwayland-egl.so missing 'wl_drm_interface'

[Iskren Chernev]

Are you sure you make && make install the wayland library first, and then
the demo? Also double check all environmental variables from the build
tutorial. You may also add
PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1
because on my system pkg-config just skipped some libraries.

Iskren
