Problems with vim-pathogen on mac osx - macos

Question

I have recently moved from Ubuntu to Mac osx. And my first thing is to bring my vim with me.
I downloaded source from vim.org and compiled with gcc.( I'll put the version output at the bottom of my post)
I added pathogen.vim to ~/.vim/autoload directory. But when I add the code in ~/.vim/vimrc:
execute pathogen#infect()
I got errors when tring to start vim, here is the error output:
Error detected while processing /Users/jack/.vim/vimrc:
line 3:
E117: Unknown function: pathogen#infect
E15: Invalid expression: pathogen#infect()
Press ENTER or type command to continue
First I though perhaps vim did not load pathogen.vim, but :scriptnames showed it did load!
1: ~/.vim/vimrc
2: ~/.vim/bundle/vim-pathogen/autoload/pathogen.vim
After I ran :function, something caught my attention, there is a "abort" after the infect function, I google around, and found it did not solve my problem either:
function pathogen#legacyjoin(...) abort
function pathogen#runtime_append_all_bundles(...) abort
function pathogen#surround(path) abort
function <SNR>2_Findcomplete(A, L, P)
function pathogen#uniq(list) abort
function pathogen#incubate(...) abort
function pathogen#glob(pattern) abort
function <SNR>2_warn(msg)
function pathogen#runtime_findfile(file, count) abort
function pathogen#separator() abort
function pathogen#runtime_prepend_subdirectories(path)
function pathogen#glob_directories(pattern) abort
function pathogen#infect(...) abort
function pathogen#is_disabled(path)
function pathogen#join(...) abort
function pathogen#cycle_filetype()
function pathogen#split(path) abort
function <SNR>2_find(count, cmd, file, lcd)
function pathogen#fnameescape(string) abort
function pathogen#execute(...) abort
function pathogen#helptags() abort
Can anyone help point out what should I do to solve this problem?
Here is the version output with command "vim --version":

Answer 1

I found the problem.
system vimrc file: "$VIM/vimrc"
user vimrc file: "$HOME/.vimrc"
2nd user vimrc file: "~/.vim/vimrc"
user exrc file: "$HOME/.exrc"
I set $VIM to ~/.vim, which is the same as the 2nd user vimrc file. So the vimrc file load twice.
After I change $VIM to /etc/vim, everything turns out be good.

Answer 2

I had a similar problem and found that I had not created the ~/.vim directory correctly. I created it in the root by changing directory there and typing mkdir /.vim but for some reason it was not working. Then I deleted this folder and did mkdir ~/.vim and was ably to install and use pathogen.
