unable to upgrade to mysql55-server

[Gene]

Greetings:

ZRunning 8.1 amd64. Ports are up to date (via portsnap).

I've been trying to install the port databases/mysql55-server from the older 
5.4 version. mysql55-client installed just fine. However, when I "make" the 
port I get the shown in the first listing below. So I tried 
"portmanager databases/mysql55-server -l -u"  (latest version - -0.4.1_9). 
Attempts to update produce multiple looping errors as in second listing 
below. I've found references to this error, but the latest version of 
portmanager (I thought) was supposed to fix this (or did it just eliminate 
infinite loops?).

Does anyone have an idea what might be going on here?

Thanks in advance...
