Description:
------------
I have installed pxlib version 0.6.3 using the FreeBSD ports.  Paradox.h is available in /usr/local/include.

I installed PHP 5.2.12 and Pear using the FreeBSD ports.  All is working well.

The install scripts fails with the message:
configure: error: wrong paradox lib version or lib not found. Need at least pxlib 0.6.0

Actual result:
--------------
Extension is failing to compile.
