[arch-general] File conflict between cuda and pacparser

Hello, Arch lovers, Both community/pacparser and community/cuda contain the file /usr/share/man/man3/deprecated.3.gz, so pacman prevent me from installing both packages. How can I jump over the obstacle? Maybe it's better to establish some mechanism for preventing irreleveant packages with common files. In addition, is there a dedicated mailing list for discussions on official (not AUR) packages? Something like commenting system on the AUR website is also fine.
