I remember copying some files around to get out of the infinite loop.

This problem didn't appear on my system.

Don't know if it helps you, but I have installed all the necessary
stuff from the ubuntu repositories. Synaptic lists:

libqscintilla-dev  : 1.7.1-2build2
libqscintilla2-dev : 2.4.5-1ubuntu1

libqt4-core : 4:4.7.4-0ubuntu8.1

actually, most qt libs have version 4:4.7.4-0ubuntu8.1.
