CodeBlocks is supervising the compilation. I had added the 
libraries to its recipe in the wrong order:

pthread
m
phobos2

The opposite way round it links OK, bu there's still something 
strange going on. When I try to run it, it fails with:

./compo: error while loading shared libraries: libphobos2.so.0.2: 
cannot open shared object file: No such file or directory

This is true, there is no such file. In /usr/lib/i386-linux-gnu 
there's only libphobos2.so - a real file - which in my 
understanding should be a link to an actual shared library file.

Is there a working shared Phobos library in 2.063, or is this a 
.deb file error. If I have /usr/lib/i386-linux-gnu/libphobos.a 
instead of phobos2, the program links and at least attempts to 
run. It may crash later, but that's my fault.

This is not just a CodeBlocks thing. I made a simple makefile 
instead that links the libraries in the right order. That links, 
but also fails with the missing Phobos shared library error.
