I have progressed a little further, but seem to have come to a block. As I 
wrote earlier, I need to build WebKit. According to the documentation, 
this requires:

     bison
     flex
     gperf
     Ruby [ruby-lang.org]
     ICU [site.icu-project.org]

It also seems to require fontconfig.

Since the versions of icu and fontconfig were too old, I built my own from 
source, using fontconfig-2.8.0 and icu-4.2.1 (these versions are what are 
used on CentOS 6, where I already had a successful build of Qt5).

I am using the devtoolset-1.1 version of gcc (4.7.2).

My configure command is forcing fontconfig and icu support:
./configure -R ‘\\\$$ORIGIN’ -D _X_INLINE=inline -D 
XK_dead_currency=0xfe6f -D XK_ISO_Level5_Lock=0xfe13 -D 
FC_WEIGHT_EXTRABLACK=215 -D FC_WEIGHT_ULTRABLACK=FC_WEIGHT_EXTRABLACK -v 
-opensource -qt-libpng -qt-zlib -qt-libjpeg  -nomake examples 
-qt-sql-sqlite -confirm-license -prefix /usr/lib/Qt/Qt-5.4.0-x86_64 
-widgets -no-openssl  -no-dbus -qt-xcb -no-opengl  -skip activeqt -skip 
androidextras -skip connectivity -skip enginio -skip location -skip 
macextras -skip multimedia -skip quick1 -skip sensors -skip serialport 
-skip wayland -skip webchannel -skip webkit-examples  -skip x11extras 
-c++11 -icu -fontconfig -I /usr/local/include/layout -I 
/usr/local/include/unicode -L /usr/local/lib -L /usr/local/lib/icu

This gets much further, but fails on Javascript:

Any suggestions?
