Compiling octave from hg sources

[Laurent Hoeltgen]

Hi,

after reading that the GUI had been merged to the default branch I was
curious and wanted to find out how it actually looked. So I followed the
steps from http://www.gnu.org/software/octave/get-involved.html to get
the latest sources for octave. Then I ran
./autogen.sh
./configure
make

Now the compilation fails at some point with the following message:

m-editor/find-dialog.cc: In member function 'void
find_dialog::search_next()':
m-editor/find-dialog.cc:150:39: error: no matching function for call to

Any ideas why I get this error? Could it be that octave requires a more
recent version of the qt libs than those in Ubuntu 11.10 repos?
