error building GUI on Mac OS-X 10.6.8

[Thomas Yengst]

I successfully built the development version with help from Ben. Finally, 
success on OS-X. Now I'm trying to build Jacob's GUI and run into something 
that I haven't seen on the maintainers list.

I did the following;:
hg update gui
hg pull
cd gui
qmake
make

... and got fairly far into the compile before....

m-editor/find-dialog.cc: In member function ‘void find_dialog::search_next()’:
m-editor/find-dialog.cc:150: error: no matching function for call to 
‘QsciScintilla::findFirst(QString, bool, bool, bool, bool, bool, int&, int&, 
bool, bool)’
/opt/local/include/Qsci/qsciscintilla.h:606: note: candidates are: virtual bool 
QsciScintilla::findFirst(const QString&, bool, bool, bool, bool, bool, int, 
int, bool)
make[1]: *** [find-dialog.o] Error 1
make: *** [sub-src-make_default] Error 2

I've got qscintilla-2.4.6_0.darwin_10.x86_64 and qt4-mac installed via 
macports. Not sure what other dependencies are required.
