1) Bump lib's version, since qt-2.1.0 loses lower compatibility
with qt-2.0.2 but has only upper compatibility. (new qt binary
does not work with old qt library)
2) Install libqgl.a (it works with its examples) in addition to libqt,
so added LIB_DEPENDS to MesaGL.
3) JPEG support from extension had been included to the main library.
4) 'examples' and 'tutorials' are no longer built with port building,
since they are never installed. If you want them, set
QTDIR=/usr/ports/x11-toolkits/qt21/work and just type 'gmake' in each
directories.
Some ideas obtained from qt145. :)
