In my personal libraries, I also prefer to maintain a connection with Common Lisp idioms and syntax as much as possible, to avoid context switching. Of course, if I would develop public libraries I would try to avoid it. Common Lisp perspective seems not favoured by main Emacs developers, although I know a few representative ones that do favour cl-lib parlance.

In any case, I use el-get to manage the external packages. el-get allows to fecth directly from EmacsWiki. I have this in my init.el:

(el-get-bundle macro-utils)

Which nicely allows one to use with-gensyms, as you asked, and also once-only:

(defmacro double (x)
(once-only (x)
  `(+ ,x ,x)))
