Comment (by mojca@…):

 For me the solution was to replace
 {{{
 /opt/local/libcodeblocks.dylib
 }}}
 by
 {{{
 ../sdk/.libs/libcodeblocks.dylib
 }}}
 in the following command that creates the codeblocks binary:
 {{{
 /usr/bin/clang++ -O2 -ffast-math -DCB_AUTOCONF -pipe -Os -arch x86_64
 -arch i386 -stdlib=libstdc++ -fPIC -DPIC -fexceptions

 Now I'm buffled because I don't understand the following `Makefile` rules.

 {{{
 am_codeblocks_OBJECTS = app.$(OBJEXT) appglobals.$(OBJEXT) \
         backtracedlg.$(OBJEXT) breakpointsdlg.$(OBJEXT) \
         compilersettingsdlg.$(OBJEXT) cpuregistersdlg.$(OBJEXT) \
         crashhandler.$(OBJEXT) debugger_interface_creator.$(OBJEXT) \
         debuggermenu.$(OBJEXT) debuggersettingscommonpanel.$(OBJEXT) \
         debuggersettingsdlg.$(OBJEXT) debuggersettingspanel.$(OBJEXT) \
         disassemblydlg.$(OBJEXT) dlgabout.$(OBJEXT) \
         dlgaboutplugin.$(OBJEXT) environmentsettingsdlg.$(OBJEXT) \
         examinememorydlg.$(OBJEXT) infopane.$(OBJEXT) main.$(OBJEXT) \
         notebookstyles.$(OBJEXT) prefix.$(OBJEXT) printdlg.$(OBJEXT) \
         scriptconsole.$(OBJEXT) scriptingsettingsdlg.$(OBJEXT) \
         splashscreen.$(OBJEXT) startherepage.$(OBJEXT) \
         switcherdlg.$(OBJEXT) threadsdlg.$(OBJEXT) \
         watchesdlg.$(OBJEXT)
 codeblocks_OBJECTS = $(am_codeblocks_OBJECTS)

 codeblocks_LDADD = -L../sdk -lcodeblocks \
         $(WX_LIBS) \
         $(WX_GTK2_LIBS)

 codeblocks$(EXEEXT): $(codeblocks_OBJECTS) $(codeblocks_DEPENDENCIES)
 $(EXTRA_codeblocks_DEPENDENCIES)~
         @rm -f codeblocks$(EXEEXT)
         $(CXXLINK) $(codeblocks_OBJECTS) $(codeblocks_LDADD) $(LIBS)
 }}}

 The variable `$(codeblocks_OBJECTS)` is:
 {{{
 app.o appglobals.o backtracedlg.o breakpointsdlg.o compilersettingsdlg.o
 cpuregistersdlg.o crashhandler.o debugger_interface_creator.o
 debuggermenu.o debuggersettingscommonpanel.o debuggersettingsdlg.o
 debuggersettingspanel.o disassemblydlg.o dlgabout.o dlgaboutplugin.o
 environmentsettingsdlg.o examinememorydlg.o infopane.o main.o
 notebookstyles.o prefix.o printdlg.o scriptconsole.o
 scriptingsettingsdlg.o splashscreen.o startherepage.o switcherdlg.o
 threadsdlg.o watchesdlg.o
 }}}
 and `$(WX_LIBS)` start with:
 {{{
 -L/opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxGTK/2.8/lib
 ...
 }}}
 So how does the
 {{{
 -L../sdk -lcodeblocks
 }}}
 part of `$(codeblocks_LDADD)` result in
 {{{
 -Wl,-headerpad_max_install_names -L/opt/local/lib -L../sdk
 /opt/local/lib/libcodeblocks.dylib
 }}}
 ?
