After finding out I couldn’t login to my Movable Type admin interface to add stuff to this blog, then reading this and this, then downloading this from here, then unpacking the tarball into a new subdirectory, cd‘ing into the dist subdirectory (in my case, /tmp/db-4.1.25/dist), then make and then cd‘ing to my Movable Type database directory, and running

/tmp/db-4.1.25/dist/db_upgrade *.db *.idx

(as described here) … after all that, I can log back in and actually post this.

This is all because I updated the install of DB_File from CPAN on my main server here. Bleh.
