Maybe this due to the version of gpg I use (1.4.12 from Debian sid)
but I get an error

$ gpg --batch --no-options --no-default-keyring --trust-model=always \
     --keyring "$KEYRING" \
     --armor -o "$POPCONGPG" -r "$POPCONKEY" --encrypt "$POPCON"

gpg: keyblock resource `/root/.gnupg/secring.gpg': file open error
gpg: fatal: /root/.gnupg: directory does not exist!
secmem usage: 1408/1408 bytes in 2/2 blocks of pool 1408/32768
