With gpg2 you can do:

  gpg2 --passwd KEYID

Of course it will use the pinentry to ask for the old an new passphrase.
You may use a pinentry wrapper as usual or with 2.1-beta the pinentry
loopback mode.

GPGME has 

  /* Change the passphrase for KEY.  FLAGS is reserved for future use
     and must be passed as 0.  This is the synchronous variant.  */
  gpgme_error_t
  gpgme_op_passwd (gpgme_ctx_t ctx, gpgme_key_t key, unsigned int flags);

this convenience function.
