Hi Giles,
QTDIR and QMAKESPEC need to be set. Strangely, they are not set on my system but everything still works. Try:
export QTDIR=/usr/lib64/qt4/
export QMAKESPEC=linux-g++-64
I guessed you QMAKESPEC so you might want to use a different one.
Please also give the PATH solution a try! The QMAKESPEC problem could do away.
Regards,
Peter
