That doesn't help as you don't have to export secret keys but have to 
import them.

For some reason it is not possible (with 1.4.x and 2.0.x) to import 
secret components for a key which is already part of the secret keyring. 
Thus you have to 

a) either change the passphrase of single components within the secret 
keyring (which GnuPG doesn't support)

b) or import a secret key file which already contains components with 
different passphrases.
