ozpost shipping module

Network Connectivity test FAILED
Is cURL installed on your server? (it needs to be). If so, this may be a temporary glitch, try again in a few minutes.
Installation will NOT continue.

I have curl enabled in php5.2.9, but also tried it unenabled.

There is no way that it will work without cURL.

I tried switching lines 70-71 of \includes\modules\shipping\ozpost.php ie
$this->SERVER = 'ozpost.vcsweb.com';
// $this->SERVER = 'http://localhost/zencart/' ;
but to no avail.

No reason to expect that to work either, unless you happen to be running a quotation server on your own machine :-)

Are there other switches?

No.

In doing the upgrade, however, I did note that one of your files was based on a 139b version.

Firstly, I have no idea if you are referring to an upgrade of the ozpost module, or if you are referring to an upgrade of zencart to 1.3.9b. Perhaps both.
Either way, I must ask the question, was your previous install of ozpost working correctly, and if so, what version was it.

As for "I did note that one of your files was based on a 139b version" this isn't quite true, it (actually, "they" as there are three of them) are based on a much older 1.3.7 or 1.3.8 version of zencart.
The purpose of them is clearly detailed within the .txt files that are supplied with all ozpost distribution packages.

Anyway, as for solving your problem, the error message is clearly indicating that there is (or was) a problem connecting to the server. A problem with cURL is just one of the *possible* causes of this problem. Other possible problems include temporary failure of the server, a firewall issue (client or server end), a routing/networking issue. a problem with the nameservers, and so forth.

The *first* thing you need to do though is ensure that cURL really is availalble and working. zencart has a program for this in the 'extras' folder.

After confirming that cURL is ok you/we will need to start to investigate why it can't (apparently) connect to the ozpost server. Depending on your skills/knowledge you may need to involve your webhost with this, however it is possible that there is a bug/flaw in the code that does the checking, so I propose this may be the easiest next step..

To do this, load /modules/shipping/ozpost.php into a text editor, then comment out (or delete) lines 525 - 532 and resave the file. Please report your results.
