I think the Julia version of Pythonic is "Julian." My understanding on the Slicot licensing situation is that 5.0 was initially released as GPL, and this is the version that Debian uses, but since then it was taken down and re-released under a different license. We can follow the Homebrew formula's lead and use the Debian repo as a source, unless you needed to make tons of changes to files that were in the tarball. I believe the convention with Julia packages is to minimize the amount of non-Julia source. Hopefully someone who is interested in control, has experience with BinDeps, and has some time can help out here.
