DCD 0 symbols cached?

[Tom]

Total newbie to D, trying to get it to play nice with Neovim 
using ncm2-d and DCD.

Issue: DCD never caches any symbols even when I point it directly 
to DMD's include files. Hate to ask for tech support on this 
forum but it's all I've got, Googling has brought no luck.

Using dcd version v0.11.0




Output from dcd-server -I /usr/include/dmd/phobos -I 
/usr/include/dmd/druntime/import :

Any tips or guidance would be greatly appreciated. Thank you.
