scdaemon.conf missing from gpg directory

I tried to setup gpg for use with a smartcard, but the instructions specified edits to scdaemon.conf, which for some reason is missing from the .gnupg folder in the home directory. The folder does contain other files, and gpg seems to be working correctly. Using find to look for scdaemon.conf turned up nothing, reinstalling gpg and scdaemon didn't resolve the issue. Does anyone know what the issue might be? Thanks.
