How to avoid WSRegister* on a Free Pascal .dll/.so

Question

I finally had success compiling a "blank" Apache module, but now I've hit a rather annoying snag.

I want to communicate with a MongoDB server and I opted for the only lib around for FreePascal/Lazarus, pebongo.

Dependency for pebongo is synapse.

Somehow I'm getting "/usr/lib/apache2/modules/mod_visius.so: undefined symbol: WSRegisterCustomImageList" when loading my module into Apache.

I've tracked down the symbols onto Menus.pp, I think, and lazarusall(something) also plays a role in this. Again, I think :)

How should I avoid those WSRegister* symbols showing up?
