"Unpacked" sounds like you're using a tarball, but unfortunately I see 
that word is also used in the tutorial. I hope you are using a clone of 
the stable or master branch rather than an old tarball.

If you did a "make" everything would have been built, including Qt. If 
that was successful, then "make qt" should have said something like 
"Nothing to be done for `qt'".

You didn't have to do that. The pkg-config in MXE already knows about 
that directory. Where the tutorial talks about this, it's about *custom" 
additional directories you might need.

It's difficult to account for this. Surely if i686-pc-mingw32-qmake is 
executed from ~/mxe/usr/bin then i686-pc-mingw32-g++ is there too. Have 
you tried "which i686-pc-mingw32-g++"? Also try "which 
i686-pc-mingw32-qmake" to make sure you're running the one you think you 
are running.
