I don't know about the Debian system, but wouldn't the numbers have to
match (i.e., 19 vs 20)?

If you can't find the prebuilt -dev package, try building from source as
suggested here:
https://www.nongnu.org/ada-mode/ada-mode.html#Building-GNATCOLL-2019 -
probably best to install in a private location, not over the
system. Also, when you get to the Github repo, the v21.0.0 package may
have compilation issues depending on your compiler: there are very few
changes between that version and the latest commit.

Since the wisi parser relies on the facilities provided by these two
packages, that is *guaranteed* not to work!
