[Slackbuilds-users] qt5 is sorely in need of an update

[orbea at fredslev.dk]

Well I hit a roadblock with Qt-5.11 on 14.2.

With '-system-harfbuzz' it bails on configure because harfbuzz is too
old, with '-qt-harfbuzz' it fails to build late in the ninja stage and
with '-no-harfbuzz' it around the same place with errors indicating it
misses harfbuzz. The obvious solution would be to update harfbuzz, but
that is easier said than done for 14.2.

Also I forgot to mention enum34 is a new dependency of PyQt5,
fortunately the version at SBo is both up to date and adequate.
