I have my keys stored in $HOME/.gnupg
which is where gnupg v1 expects them.
Using gnupg2:

 gpg2 --export -a "Jeff Deifik"
-----BEGIN PGP PUBLIC KEY BLOCK-----

mQGiBEt8tlURBACkuHVVgDFnNK9JeY9JbaoBwyaiCebmUPbp66YIMjRi4LKHOsYG
zVR0XUlYfB9M7S6td8HEOhakjpjXFdSzBqWzFEhBKhnl4r2lPU7WxH/+f8Tmyuuo
...


gpg2 --export-secret-key -a "Jeff Deifik"
gpg: key XXX: error receiving key from agent: No such device or address
- skipped
gpg: key FXXX: error receiving key from agent: No such device or address
- skipped
gpg: key XXX: error receiving key from agent: No such device or address
- skipped
gpg: key XXX: error receiving key from agent: No such device or address
- skipped
gpg: WARNING: nothing exported

(I replaced the hex with XXX)

I suspect there is a problem with the pinentry and/or agent.
The pinentry thing seems to be a new thing with gnupg2.
