I tried with dh_makeshlibs, but the results are weird, 
debian/yade-svn1145-dgb/DEBIAN/shlibs has:

libyade base yade-svn1145-dbg
libyade loki yade-svn1145-dbg
libyade multimethods yade-svn1145-dbg
libyade factory yade-svn1145-dbg
libyade serialization yade-svn1145-dbg
libyade-computational geometry yade-svn1145-dbg
libyade opengl yade-svn1145-dbg
libyade-serialization qt yade-svn1145-dbg

Precisely: 1. only very few libs are mentioned (only those that contain 
hyphen), 2. the last hyphen in the library name is replaced by space. I 
verified soname's of all plugins with objdump, they are embedded correctly. 
  Perplexed.

I I read this now, 
http://www.netfort.gr.jp/~dancer/column/libpkg-guide/libpkg-guide.html#rpath 
, which summarizes the point. I think it is OK for yade since plugins are 
not supposed to be linked with anything else except other plugin in the very 
same package; and perhaps externally compiled modules, and that is handled 
by pkg-config. Rpath simplifies plugin loading a lot, which was the reason I 
introduced it in the first place.

Thanks, is on the TODO list.
