perl-DB_File isn't exactly deprecated.  It is not marked as deprecated at http://perldoc.perl.org/DB_File.html.  If it is marked as deprecated, can you provide a link to that?

Are there specific features you want to use that are not available via the perl-DB_File interfaces?

logconv.pl uses very basic features of BDB.  I'm not sure how we could significantly improve logconv.pl by using BerkeleyDB instead of DB_File.

I would rather rewrite logconv in some other language (like python, or something newer like go? rust?), or figure out how to use off-the-shelf 3rd party logging parsers.

The documentation says this:
"Using DB_File with Berkeley DB version 2 or greater

Although DB_File is intended to be used with Berkeley DB version 1, it can also be used with version 2, 3 or 4. In this case the interface is limited to the functionality provided by Berkeley DB 1.x. Anywhere the version 2 or greater interface differs, DB_File arranges for it to work like version 1. This feature allows DB_File scripts that were built with version 1 to be migrated to version 2 or greater without any changes.

If you want to make use of the new features available in Berkeley DB 2.x or greater, use the Perl module BerkeleyDB instead."

And in fact perl-DB_File can use bdb 5.x:

$ cat /etc/fedora-release 
Fedora release 23 (Twenty Three)
$ ldd /usr/lib64/perl5/vendor_perl/auto/DB_File/DB_File.so
...
    libdb-5.3.so => /lib64/libdb-5.3.so (0x00007f5979411000)
