[Development] Compiling Qt5 Alpha on Linux fails

[Peter Rullmann]

Hi,

I'm trying to compile Qt5 Alpha on Linux, but got stuck.

I am running Ubuntu 11.04, but my colleague running 11.10 has exactly the
same issues.

I built using `./configure -opensource -confirm-license -nomake tests` and
`sudo ./build -j 2`

Here are the Problems I had:
* I had to run ./build with sudo, which is not documented in the
   instructions
* There was a problem in 'qt3d/src/quick3d', which I worked around by
   running make in that directory by hand and creating the target directory
   beforehand.
* 'gperf' seems to be needed, but is not listed in the dependencies.
* Then I got stuck in qtwebkit:

I had no luck working around this problem yet.
Does somebody have any suggestions? Did I forget something? Should I
provide more Information?
Could it be that previous installed git builds of Qt5 or older versions of
Qt are causing problems?

Regards,
Peter
