Hi Jerry,
Sorry the missing details - but well spotted: I do use ubuntu and it was
with the 12.04 upgrade that I experienced the issue.
Your advice was spot on - sudo apt-get install python-numpy solved the job,
and when I ran pip afterwards I received the message that "requirements are
already satisfied".

Thank you again - I will keep it in mind that
"apt-get install python-some_packages" may be the right way about it on
