undefined symbol: _Dmain when loading library at runtime on Linux

[David Nadlinger]

The short answer is: Shared D libraries, especially dynamically loading 
them, is not supported by LDC. We are going implement this once upstream 
druntime actually supports runtime loading (2.064). So, even the 
versions that "work fine" do so just by accident. There are much bigger 
problems that this, even with compile-time linked shared libraries.

dlfcn - you mean libdl?
