Excavations have shown that rubypython can not find libpython2.7.so, because the public library located in /usr/lib/x86_64-linux-gnu/:

-rw-r--r-- 1 root root 3262616 Jun  2 18:19 /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0

Options to fix: add the path matching condition /usr/lib/*-linux-gnu/ to the search libraries path.

I tried building rubypython from hg source, but the gemspec which Hoe generated was out of date (particularly gem.files). Consider using a live gemspec which calls hg manifest to list the files. Here is one such gemspec generated by Ore.
