There is this variant of NetHack 3.4.3 called NetHack brass; download it from http://www11.cds.ne.jp/~youkan/nethack/index_e.html

Kernigh distributes and recommends its brass interface patch; download it from DownloadFile.

The correct thing to do is to download the zip of NetHack brass 040923, unzip it, and download and apply the brass interface patch.
