macports registry error when runtime dependency installed but not active

[Jeremy Lavergne]

I was updating akonadi using trunk today, and it error’d out complaining that virtuoso wasn’t installed.

--->  Configuring akonadi
Registry error: virtuoso not registered as installed & active.

Turns out virtuoso was installed, just not activated.

Is there a reason MacPorts is unable to activate this on its own and get on to building?
