Hello, twopaco has entered testing (yay!), thus I gave its reverse dependency, pufferfish (ITP bug #944785), a look. pufferfish carries embedded copies of twopaco and ntcard with a modified build system to create static (or is it shared?) libraries for these two and then links pufferfish with them. For Debian twopaco and ntcard have been un-embedded from pufferfish and packaged as separate binary packages instead. However, they do not build neither shared nor static libraries, just executables.
I think we can get around by patching twopaco and ntcard builds to include static libraries in their binary packages. Does this sound right? Best, Andrius
