Oh, `fs sysname` returning `amd64_ubuntu1804` and not
`amd64_ubuntu2204` is not going to go well with building barnowl for
this release. The versions of perl in 18.04 and 22.04 are different,
which is why the existing barnowl build for 18.04 doesn't work on the
new dialup. If `@sys` can't distinguish them then we have no place to
put the new build.
glasgall was the last person to build barnowl for the locker, IIRC,
and I don't know how much she remembers at this point. I know I've
forgotten everything I ever knew about how to set up the perl stuff,
but I know that's a necessary step.

my guess is that we just need to rebuild barnowl for 22.04.

I don't see any similar script for building and installing whatever perl li=
braries we need; currently ./configure fails with configure: error: cannot =
find perl module Module::Install::Base. Does anyone who's done a barnowl r=
elease recall the process for setting up perl for barnowl on a new arch?
