"Error: Target org.macports.activate returned: Not a directory" in py25-pyqt4

[Uldis Bojars]

I am getting this error (see below) when installing py25-pyqt4.

It has also appeared when installing some other ports (e.g.,
redland-bindings) and I am wondering if this is a known problem with a
known solution.

The port actually becomes active (trying to install or activate it
again returns a messages that a port is already active), but something
in the activation process is not finished. If the port is uninstalled,
some files remain behind and prevent you from installing this port the
next time (unless -f option is used).

Could you suggest how to fix this?

Thanks,
Uldis
