I tried to install caffe on my Arch Linux, but it prompted following errors:
$ yaourt -S caffe
......
error: file owned by 'ntl' and 'ntl-threading': 'usr/include/NTL/BasicThreadPool.h'

The reason is I installed NTL through pacman before. So the solution is uninstalling NTL first:
$ sudo pacman -R ntl
Then installing caffe successfully:
$ yaourt -S caffe
