This caught my attention.

Does it really need Berkeley DB version 1?

Or will version 2, 3 or 4 work?

If it needs db1 (which Sleepycat has deprecated), then we must add a
databases/db1 package.

Because some operating systems may not have db1. For example, in the past
db1 was included by default with glibc, but recent glibc doesn't include
db1 by default.
