All my past attempts to build Vim from sources or via MacPorts while matching MacVim's features have resulted in slow and oversized memory hogs (think 10 seconds startup).
The best solution for me is to just use MacVim's CLI binary which is located in MacVim's bundle:
Which gives you a very modern, feature-packed and speedy Vim.
I'd suggest you install it through Homebrew to easily keep it up to date. Light weight MacPorts. http://mxcl.github.com/homebrew/
