dear org-mode users - anyone using this version of emacs & encrypting via org-crypt.el ??

This works great on my laptop - I don't really want file/folder/partition encryption, just a node here and there in org-mode files.

I'm using emacs 23.2.1 with org-mode 7.01 on the laptop and this emacs with org 7.01 on the n900

mysetup:
(require 'org-crypt)
(setq org-tags-exclude-from-inheritance (quote ("crypt")))
(setq org-crypt-key "MyPassPhrase")

this works on the laptop. On the n900:
M-x org-encrypt-entry
when I type the passphrase, enter will not take the phrase. No cpu usage, just a lock. Ctrl-g stops the process throwing the message "epg-encrypt-string: Encrypt failed:exit"

Do I need to look @ the default location for my gpg program...or upgrade emacs? or ???
