The error mean you have old (5.0.x most likely) PHP headers installed and they were used when you built the extension, but you're trying to load it with new PHP.
I suggest you to reinstall PHP or remove the old headers manually (and put the new ones instead).

Sorry, my php version is 5.1.6 not 5.2.1

my php version is 5.1.6. , what you will suggest still i have to upgrade my PHP.

Doesn't matter, your PHP headers are still from 5.0.x.
But as a matter of fact, yes, I'd recommend you to upgrade to 5.2.x.
