I'm wondering if the .pike and .pmod files associated with binary modules really have to be in /usr/share/pike7.6, with symlinks there from /usr/lib/pike7.6. The situation seems similar to Perl: Debian installs all files associated with an XS module under /usr/lib, not just the shared library (.so) and mere wrappers, but also .pod files (stand-alone documentation) and larger .pm files.
