MYSQL_MODULE_TYPE builtin/external?

[Anon]

I just installed Apache, then MySQL and then compiled latest PHP4. When i did a phpinfo() to see how it all went I noticed that even though I have mysql installed and during complie time i specified the mysql dir (--with-mysql=<path to mysql), why is that MODULE_TYPE shows up as builtin? Is there a performance issue when it comes to builtin vs external?
Thank you,

I figured out why it said buitin. It was because the path to libmysqlclient.so was not specified in ld.so.conf file. BUT I AM STILL WONDERING IF THERE IS A ADVANTAGE TO USING BUILTIN vs. EXTERNAL?

Thank you,
