FYI, I've filed a bug report upstream to see if they'd be interested in
splitting things up to make them easier to package. [1]

IMO a Debian port might not be the right way to go. Clang and GCC are
packaged alongside each other without problems. If Fil-C and pizlonated
libraries and applications were simply part of the x86_64 build of
Debian, that would allow projects like Kicksecure and Whonix to use
pizlonated applications where possible, or to build our own code with
Fil-C, while still having access to the rest of the Debian archive.
