Compiling sigil 0.8 on LMDE

[tauran]

Hello,
I need help compiling sigil 0.8 on Linux Mint Debian Edition 64 bit.

I get

QMake version 3.0
Using Qt version 5.1.1 in /usr/lib/x86_64-linux-gnu

Please help

class QTextEdit’ has no member named ‘setPlaceholderText’

I don't believe QTextEdit had a setPlaceholderText method in Qt5.1.1.

If I had to guess, I'd say that particular section of code makes Qt5.3 an (unenforced) minimum requirement for building Sigil.
