If i understand your issue correctly, you are using a plugin named ShowFunc.vim which tries to check the major/minor version of ctags and complains if sees something that is under 5.4. Since this ctags version prints "Development" it won't be recognized.

I'm not sure if upgrading ctags would help per-se, you could grab the sources (well almost the same sources, but should work nontheless) from b4n and change the version string ctags.h and compiling it with that.

I'm not sure if this helps, maybe you could look at other vim plugins too that give you similar functionality like tagbar.

Issue exactly on ShowFunc.vim plugin. In this case tagbar: better choice. Thanks for your professional and quick reply.
