Problems with pbuilder (qt5 packaging) in Ubuntu 13.04

I see some inconsistencies in your pbuilder log:

Depends: ... libqt5core5 (>= 5.0.2), ... libqt5printsupport5 (>= 5.0.2), libqt5widgets5 (>= 5.0.2)

In the question title you claim to be running Ubuntu 13.04, but libqt5* release 5.0.2 is delivered only with Ubuntu 13.10
https://launchpad.net/ubuntu/+source/qtbase-opensource-src
The Saucy Salamander (active development) 5.0.2+dfsg1-7ubuntu2
The Raring Ringtail (current stable release) 5.0.1+dfsg-0ubuntu4

So the version of your OS, the pbuilder package you are using, and the libgt5 packages do not fit together for whatever reason.

Please provide the output of

uname -a
lsb_release -a

As you can see, the package versions for libqt5* delivered with standard Ubuntu are 5.0.1...
You have installed 5.0.2... versions from two PPAs.

What is the "depends" information for the software that you want to package? Is the >=5.0.2 dependency really required?

You have to be aware, that pbuilder usually uses just the standard repositories, and can only find the 5.0.1 versions.

If your software depends on 5.0.2, the pbuilder scripts will probably fail, unless you configure your pbuilder environment that it also has the related PPAs enabled. This would have as consequence, that the users have also to enable these PPAs if they want to install your software.

Well, part of problem is solved, now it seems qmake is missing

Can't exec "qmake": No such file or directory at /usr/share/perl5/Debian/Debhelper/Dh_Lib.pm line 215.
dh_auto_configure: qmake -makefile -nocache QMAKE_STRIP=: PREFIX=/usr failed to to execute: No such file or directory
make: *** [build] Error 2
dpkg-buildpackage: error: debian/rules build gave error exit status 2
E: Failed autobuilding of package
I: unmounting dev/pts filesystem
I: unmounting proc filesystem
I: cleaning the build env
I: removing directory /var/cache/pbuilder/build//11464 and its subdirectories

What do I need to include in control file so system can find qmake.

Maybe adding qtchooser or qt4-qmake or qt5-qmake to build-depends makes qmake available to the pbuilder?

I still have problems, now I got error which I never seen. Do you know what it means:

qmake: could not find a Qt installation of ''
dh_auto_configure: qmake -makefile -nocache QMAKE_STRIP=: PREFIX=/usr returned exit code 1
make: *** [build] Error 25
dpkg-buildpackage: error: debian/rules build gave error exit status 2

I: unmounting dev/pts filesystem

I: cleaning the build env
I: removing directory /var/cache/pbuilder/build//4158 and its subdirectories

Sorry, this goes beyond my knowledge. I have no experience with qt5.

Which qmake has been used by pbuilder (of qt4 or qt5)?
Can you provide a few lines more of the build log, previous to the snippet you posted?

This is full log

Is there someone else who knows solution for this problem

Thank you, it's ok now

Thanks Manfred Hampl, that solved my question.
