I've just attempted pkg upgrade with pkg-1.5.1

=================================================
Fetching mysql56-client-5.6.23.txz: 100%    2 MiB   2.1MB/s    00:01    
Fetching mysql56-server-5.6.23.txz: 100%    8 MiB   1.7MB/s    00:05

plugin(l)
dependency rule: package akonadi(l) depends on: qt4-mysql-plugin(r)qt4-mysql-

plugin-4.8.6

Conflicts with the existing packages have been found.
One more solver iteration is needed to resolve them.
=================================================

A second run didn't fix the problem, nor did replying "no" to the "remove it 
from request"question.
A further oddity is that subsequent runs ended with the message "Your packages 
are up to date" which was certainly incorrect.

I deleted  qt4-mysql-plugin and tried again but got similar errors for p5-DBD-
mysql

=================================================
pkg: Cannot solve problem using SAT solver:
upgrade rule: upgrade local p5-DBD-mysql-4.031 to remote p5-DBD-mysql-4.031
cannot install package p5-DBD-mysql, remove it from request? [Y/n]: y
pkg: cannot find p5-DBD-mysql in the request
pkg: cannot solve job using SAT solver
Checking integrity... done (0 conflicting)
Your packages are up to date.

=================================================

Prior to the update there had been conflicting requirements for mysql55 and 
mysql56 which I'd got round by building p5-DBD-mysql from ports to use 
mysql55-client.

After deleting p5-DBD-mysq I was able to complete the upgrade without errors 
and then reinstall  p5-DBD-mysq as a package.

I was able to work round these errors but am wondering if the solver ought to 
have been able to handle them or perhaps produce less cryptic error messages?
