Vim comes with a perl indent file. You might want to enable filetype
specific indenting using :filetype indent on

See http://vimhelp.appspot.com/vim_faq.txt.html#faq-27.1

You might also want to enable filetype plugins, that usually set some
defaults for specific filetypes (e.g. the perl.vim filetype sets the
smartindent setting)
http://vimhelp.appspot.com/vim_faq.txt.html#faq-26.5

Note, filetype specific settings can also be put into their own files:
