Hello!

I have a problem compiling CGAL ipelets on OS X 10.7.5. Ipe version is
7.1.4. 
CGAL 4.2.0  (installed via Macports, cgal @4.2_0+demos+qt4)
Demos and examples compile smoothly.

Now I want to install CGAL ipelets.
I do


/*cmake -DIPE_INCLUDE_DIR=/opt/local/include -DIPE_LIBRARY_DIR=/opt/local/
.*/

and get 

/-- Build type: Release
-- USING CXXFLAGS = '-pipe -Os -arch x86_64  -O3 -DNDEBUG'
-- USING EXEFLAGS = ' -L/opt/local/lib -Wl,-headerpad_max_install_names
-arch x86_64
-Wl,-dylib_file,/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib
'

-- Configuring done
-- Generating done
-- Build files have been written to:
/opt/local/share/cgal/demo/CGAL_ipelets/

Then I do 

/*make install*/

and get


/Scanning dependencies of target CGAL_alpha_shapes
Linking CXX shared module libCGAL_alpha_shapes.so
Undefined symbols for architecture x86_64:
  "ipe::Lex::getInt()", referenced from:

make[1]: *** [CMakeFiles/CGAL_alpha_shapes.dir/all] Error 2
make: *** [all] Error 2/


Does anybody have an idea how to deal with that?
Best regards,
Elena
