[Libreoffice] Compilation failed in slideshow/source/engine

Hello,

On a Debian testing x86 32 bits, here is my autogen.lastrun :
--enable-ext-barcode
--enable-ext-diagram
--enable-ext-google-docs--enable-ext-hunart
--enable-ext-lightproof
--enable-ext-lightproof
--enable-ext-mysql-connector
--enable-ext-nlpsolver
--enable-ext-numbertext
--enable-ext-oooblogger
--enable-ext-pdfimport
--enable-ext-presenter-console
--enable-ext-presenter-minimizer
--enable-ext-presenter-ui
--enable-ext-report-builder
--enable-ext-scripting-beanshell
--enable-ext-scripting-javascript
--enable-ext-scripting-python
--enable-ext-typo
--enable-ext-validator
--enable-ext-watch-window
--enable-ext-wiki-publisher
--enable-graphite
--enable-evolution2
--enable-epm
--enable-gio
--enable-kde4
--enable-binfilter
--enable-extra-gallery
--enable-extra-template
--enable-extra-sample
--with-system-mysql
--disable-gnome-vfs

and here is the error :
=============

The file compile-libreoffice/libo/slideshow/source/engine/makefile.mk 
contains this
.IF "$(ENABLE_PRESENTER_EXTRA_UI)"=="YES"
ENABLE_PRESENTER_EXTRA_UI is not used anymore  // (line 41)
.ENDIF

Must these lines be removed or the removing should be much bigger ?

Julien.
