 I've attempted two complete reinstalls of MacPorts. I've changed
 permissions, cleaned ports, tried manually fetching and installing ports,
 and I cannot accomplish any successful installation. I have managed to
 manually fetch the ports once or twice, but after that it denies any
 installation. I can successfully "self update" Macports though.

 I get this same issue with every port attempted to install. After hours
 and hours of searching through various past tickets, i've given up and
 hope that you can help.
