hplip not work after Big Merge(tm)

After the Big Merge(tm) hplip not work because the qt4 package has been removed from -current.

It's possible to rebuild the package using qt5 instead of qt4 package using this simple patch in hplip.SlackBuild:

Code:30c30
< BUILD=${BUILD:-3}
---
> BUILD=${BUILD:-4}
153c153,154
< --enable-qt4 \
---
> --enable-qt5 \
> --disable-qt4 \
Thanks Pat for Big Merge(tm) :)
