 Indeed, /opt/local/lib/libpython3.4m is not provided by python34.

 However, anjuta +python27 succeeds due to the fact that python27 installs
 a symbolic link to the python27 library for this purpose in post-destroot


 {{{
 post-destroot {
     set framewpath ${frameworks_dir}/Python.framework
     set framewdir  ${framewpath}/Versions/${branch}

     foreach dir { Headers Resources Python Versions/Current } {
         file delete ${destroot}${framewpath}/${dir}
     }

     ln -s ${framewdir}/share/man/man1/python${branch}.1
 ${destroot}${prefix}/share/man/man1/
     ln -s ${framewdir}/Python
 ${destroot}${prefix}/lib/libpython${branch}.dylib

     foreach unversionedFile {2to3 2to3-2 idle idle2 pydoc pydoc2 python
 python2 python-config python2-config pythonw pythonw2 smtpd.py smtpd2.py}
 {
         delete ${destroot}${prefix}/bin/${unversionedFile}
     }

     # remove -arch flags from the config
     reinplace -E {s|-arch [a-z0-9_]+||g} \
         ${destroot}${framewdir}/lib/python${branch}/config/Makefile \
         ${destroot}${framewdir}/lib/python${branch}/_sysconfigdata.py
 }
 }}}

 The python34 (and the python3* ports in general) skip this link
 {{{
 post-destroot {
    set framewpath ${frameworks_dir}/Python.framework
    set framewdir  ${framewpath}/Versions/${branch}

    foreach dir { Headers Resources Python Versions/Current } {
       file delete ${destroot}${framewpath}/${dir}
    }

    ln -s ${framewdir}/share/man/man1/python${branch}.1
 ${destroot}${prefix}/share/man/man1/

    # Without this, LINKFORSHARED is set to
    # ... $(PYTHONFRAMEWORKDIR)/Versions/$(VERSION)/$(PYTHONFRAMEWORK)
    # (this becomes Python.framework/Versions/3.2/Python) which doesn't
    # quite work (see ticket #15099); instead specifically list the
    # full path to the proper Python framework file (which becomes
    # ${prefix}/Library/Frameworks/Python.framework/Versions/3.2/Python)
     reinplace {s|^\(LINKFORSHARED=.*\)$(PYTHONFRAMEWORKDIR).*$|\1
 $(PYTHONFRAMEWORKINSTALLDIR)/Versions/$(VERSION)/$(PYTHONFRAMEWORK)|}
 ${destroot}${framewdir}/lib/python${branch}/$confdir/Makefile

    # remove -arch flags from the config
     reinplace -E {s|-arch [a-z0-9_]+||g} \
        ${destroot}${framewdir}/lib/python${branch}/$confdir/Makefile
     foreach unversioned {2to3 idle3 pydoc3 python3 python3-config pyvenv}
 {
         delete ${destroot}${prefix}/bin/${unversioned}
     }
 }
 }}}

 Manually creating the link fixes the problem.  Is there any reason, that
 this action should not be added to the python3 post-destroot phase?
