The qwt & qwtpolar SlackBuilds are attached for testing prior to 
submission. To incorporate the changes, the qgis.info file should name 
qwtpolar instead of qwt in the REQUIRES line (qwtpolar already REQUIRES 
qwt); in the qgis.SlackBuild, configure to use external qwtpolar and 
give location of the qwtpolar include directory by adding:
-DWITH_INTERNAL_QWTPOLAR="off" \
-DQWTPOLAR_INCLUDE_DIR=/usr/include/qwt \

For those interested, the SlackBuilds which have qwt as an optional 
build dependency are ophcrack and gnuradio. AFAICS this proposed qwt 
update has no effect on either of these (although for different reasons).

In fact ophcrack, which REQUIRES qwt when the build environment has 
GRAPH=yes, doesn't even build with the existing qwt version so updating 
qwt has no effect on ophcrack. An even older qwt in the 5.x.x series is 
required for ophcrack to build with GRAPH=yes.

The SlackBuild for gnuradio builds just fine with the updated qwt 
version. No particular options need to be set; if qwt is installed at 
build time, it is detected and (presumably) used. I say 'presumably' 
because I'm unsure how to test the runtime. Does anyone else know how to 
run gnuradio and perhaps test this more thoroughly?
