How can i prevent my vim plugins being overridden by older ones?

Question

I have installed MacVim via homebrew, and pathogen via downloading the pathogen.vim file to my ~/.vim/autoload directory. I have got cloned the vim-perl plugin into ~/.vim/bundle directory.

However, when i open a perl file, it uses the syntax highlighting from the perl.vim file included with MacVimand not my downloaded plugin. This is the output of :scriptnames. Note all the MacVim supplied plugins are there and I think the perl ones listed last overwrite my downloaded plugin:

1: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/vimrc

38: ~/.vim/bundle/vim-perl/indent/perl.vim
39: /usr/local/Cellar/macvim/7.4-73/MacVim.app/Contents/Resources/vim/runtime/indent/perl.vim

Here is my ~/.vimrc file

set shell=/bin/sh

call pathogen#infect()

filetype off
syntax on
filetype plugin indent on

If I :so ~/.vim/bundle/vim-perl/syntax/perl.vim then the file syntax highlights correctly.

How can I prevent the MacVim bundled ones overriding?

Nope, that made no difference. The files are still there in the same order in `:scriptnames` — cubabit, Nov 13 '14 at 22:56
`runtimepath=~/.vim,~/.vim/bundle/default,~/.vim/bundle/vim-javascript,~/.vim/bundle/vim-perl,/usr/local/Cellar/macvim/7.4-73_1/MacVim.app/Contents/Resources/vim/vimfiles,/usr/local/Cellar/macvim/7.4-73_1/MacVim.app/Contents/Resources/vim/runtime,/usr/local/Cellar/macvim/7.4-73_1/MacVim.app/Contents/Resources/vim/vimfiles/after,~/.vim/after` — cubabit, Nov 13 '14 at 23:18
Looks like my bad :( It was loading the syntax but some was disabled because I had not put it in `after/...` — cubabit, Nov 14 '14 at 18:11

The inclusion guard (if exists("b:current_syntax")) should prevent the default Perl syntax script from having any effect (after your custom one has been sourced).

As a workaround, you could move your own script from ~/.vim/bundle/vim-perl/syntax/perl.vim to ~/.vim/bundle/vim-perl/after/syntax/perl.vim, or alternatively create a ~/.vim/after/syntax/perl.vim script with

so ~/.vim/bundle/vim-perl/syntax/perl.vim

in it.
