question regards to external library

[Joseph Yee <jyee@xxxxxxxxxxxxxxx>]

Greeting,

First time poster.  I have made some changes to external library (ie. 
IMAP c-client) and wonder if I have to rebuild the whole PHP (PHP 5.2.5) 
or I could do some make extension, and how?  I looked into PHP manual, 
but found nothing.  Any pointers would be appreciated.

Thanks in advance.

Joseph
