Extending pre-compiled libphp4.so

Is there a way to take a currently functioning extension that is being built into a libphp4.so and build it as a shared library so that I can be sent it to another apache box with a libphp4.so that has not been built with integrated extension support (./configure --with-myextension) I want the PHP function dl("myextension.so) to load the function without having to compile the extension into libphp4.so. What looks like the easy way to do this is to modify the Makefile in the extension directory to generate a shared library instead of just an extension.lo file. Any ideas or advice? Mark Diener
