Verifying Qt 3.x Multithreaded (MT) build environment ... fail

Unable to find Qt 'mkspecs'.  Perhaps you need to
install the Qt 3 development utilities.  You may download
them either from the vendor of your operating system
or from http://www.trolltech.com/

If you're sure you have the Qt development utilities
installed, you might try using the --qtdir option.
