Using this method of requiring languages,
;; emacs-lisp
(org-babel-do-load-languages
'org-babel-load-languages
'((perl . t)))
Works for me without issue when called from a fresh emacs (-Q). This is
the recommended way of adding support for a new language and should work
for the OP.

The two fixes seem to be either to either (1) add (require 'ob-tangle)
to all current and new language specific files, or (2) merge ob-tangle
into ob.el, so that they are both loaded by (require 'ob). It is
unfortunate that because of the recursive require there is no way to
separate a single require'd entity across multiple files.
Option (2) seems most clean to me. Unless anyone has a better idea I'll
make this change.
Best,
