Comment (by gagarine):

 Regarding cherrytree, pygtksourceview is not required anymore for later
 version of cherrytree (they moved from python to C++ apparently).

 I try to compile it on my machine but cherrytree requiere glibmm >= 2.64
 and macport provide only up to 2.58.1


 I believe cherrytree will benefit from an update. The one in the tree is
 0.39.4 and is still the python based one. Asking if an port could be
 updated is also done trough track?
