Wascana has been discontinued.
MinGW has a new package management system called mingw-get that is being maintained by the MinGW community. I now recommend you use it to manage your MinGW install and have discontinued work on Wascana. CDT will find your MinGW install automatically if you install it into C:\MinGW, add the MinGW bin directory to your PATH, or set the MINGW_HOME environment variable to the install location.
