Well, it appears that key selection is broken again in 1.07.  Trying to
update, and here's the results:

% gpg --homedir /website/.gnupg --armor --batch -r jrhett --sign --encrypt < /etc/hosts
gpg: secret key parts are not available
gpg: no default secret key: general error
gpg: [stdin]: sign+encrypt failed: general error

I did this according to standard practice, --export-secret-subkeys into a
new directory and remove the password from the key in that directory.

Here's the --debug 64
% gpg --homedir /website/.gnupg --armor --batch -r jspinks --sign --encrypt --debug 64 < /etc/hosts 
gpg: NOTE: no default option file `/website/.gnupg/options'
gpg: DBG: finish_lookup: checking key D2F0CE05 (all)(req_usage=0)
gpg: DBG:       using key D2F0CE05
gpg: DBG: finish_lookup: checking key D2F0CE05 (all)(req_usage=0)
gpg: DBG:       using key D2F0CE05
gpg: DBG: cache_user_id: already in cache
gpg: secret key parts are not available
gpg: no default secret key: general error
gpg: [stdin]: sign+encrypt failed: general error
