--- Comment #11 from Petr Pisar <ppisar at redhat.com> ---
The git tree configures against Qt4:

[...]
-----------------------------------------------------------------------------
-- The following external packages were located on your system.
-- This installation will have the extra features provided by these packages.
-----------------------------------------------------------------------------
   * QScintilla2 - QScintilla2 libraries
   * QImageBlitz - QImageBlitz library
   * Phonon - Phonon multimedia framework
   * Qwt5 for Qt4 - Qwt5 libraries for Qt4

-----------------------------------------------------------------------------
-- Congratulations! All external packages have been found.
-----------------------------------------------------------------------------


and builds successfully besides one warning:

/tmp/perlqt/qtcore/src/util.cpp: In function ‘void
XS_AUTOLOAD(PerlInterpreter*, CV*)’:
/tmp/perlqt/qtcore/src/util.cpp:2254:59: warning: converting ‘false’ to pointer
type ‘void*’ [-Wconversion-null]
         static smokeperl_object nothis = { 0, 0, 0, false };

but almost all tests fail:

[...]
3% tests passed, 30 tests failed out of 31

The log shows:

#   Failed test 'use QtCore4;'
#   at /tmp/perlqt/qtcore/t/a_loading.t line 2.
#     Tried to use 'QtCore4'.
#     Error:  Can't locate QtCore4.pm in @INC (you may need to install the
QtCore4 module) (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5
/usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5
/usr/share/perl5 .) at /tmp/perlqt/qtcore/t/a_loading.t line 2.
# BEGIN failed--compilation aborted at /tmp/perlqt/qtcore/t/a_loading.t line 2.

Obviously the tests are run without setting perl search path to the just
compiled code. If I run the tests as:

$ PERL5LIB=$PWD/blib/arch:$PWD/blib/lib make test

Then the results are much better hover, not hundred-percent:

The following tests FAILED:
          2 - perlqt_qtcore4_qapp (Failed)
          3 - perlqt_qtcore4_sigslot (Failed)
          4 - perlqt_qtcore4_sigslot_inherit (Failed)
          5 - perlqt_qtcore4_handlers (Failed)
         22 - perlqt_qsignalspy (Failed)

That's because the tests require accessible X11 server:

Command: "/bin/prove" "/tmp/perlqt/qtcore/t/c_qapp.t"
Directory: /tmp/perlqt/qtcore/t
"perlqt_qtcore4_qapp" start time: Nov 03 10:52 CET
Output:
----------------------------------------------------------
c_qapp.t: cannot connect to X server

When running the tests against Xvfb, then all the tests pass.

So the only issue is the missing path to the Perl modules.
