First port installation fails

[Richard Tobin]

I installed MacPorts-1.5.0.pkg, did a self-update, then did

  port install firefox-x11

After installing several ports, it aborted with:

--->  Activating p5-pathtools 3.25_0
Error: Target org.macports.activate returned: Image error: /opt/local/lib/perl5/5.8.8/darwin-2level/auto/Cwd/Cwd.bs is being used by the active perl5.8 port.  Please deactivate this port first, or use the -f flag to force the activation.

Presumably this should not happen.

There was no /opt/local before I started, so it can't be some stale
port.
