It's not causing any issues with respect to the services running. 
Everything runs just fine.  It's the annoying cron job error messages 
that I keep getting. :)  It's not a production server. It's a VPS I use 
for my own education in all things linux/debian.  If I screw anything 
up, it just affects me.

Ah, thank you.  I couldn't find anything on google about it.

On my VPS, I upgraded from MariaDB 5.3 to 5.5 using their repo.  Started 
getting the errors.  But I had done a little cleanup of my VPS and 
wondered if I hadn't inadvertently done something I shouldn't have. 
Googling wasn't much help although I had found the bug report Lisa 
mentioned but what had confused me was the two entries that ldd was 
spitting out.  I thought it was seeing libmysqlclient18 twice, hence my 
wondering if I had done anything in my cleanup.

In the meantime, I created a few pristine disk images of Debian Squeeze 
and Wheezy and installed mariadb and exim4-daemon-heavy and experienced 
the same problems. exim4 ran fine with the debian version of 
libmysqlclient18 installed but when mariadb replaced it, errors occurred.

I filed a bug report with mariadb and it's already being looked at.  Yay!

Thanks for everyone's comments.  Looks like Miriam's comments were on 
the money about what happened.  Hopefully, it's on the road to getting 
fixed in the next release of Mariadb.

I really appreciate being able to ask questions here.  I'm not very 
experienced and those mailing lists can be daunting sometimes.

Again, thanks.
