>Description:
	Qwt is accompanied by a file named qwt.prf, which serves as a
	"feature" include file for qmake.

	That way, qmake-based projects can make Qwt known by the line

	CONFIG += qwt

	This file is currently not installed by the port.
>How-To-Repeat:
	Add CONFIG += qwt to your Qt project's myproject.pro file, and
	run "qmake".  Without the qwt.prf file in place, no notion of
	the Qwt infrastructure will be placed in the generated Makefile.
>Fix:

	The qwt.prf file is already around in the Qwt tarball.  The
	file ought to be placed into the directory
	$(PREFIX)/share/qt4/mkspecs/features/ .
	I needed the following changes, compared to the file as
	distributed:

	    QwtBase    = /usr/local
	    INCLUDEPATH += $${QwtBase}/include/qwt
