You don't intern variables, you intern symbols (now I guess you
know that, but then: what are you trying to do?)

gensym evaluates to an already interned symbol:

  (symbol-interned? (gensym "foo"))
  => #t

... abc2652 would be an interned symbol here.

...but it is unbound (i.e. there is no value associated with it). For
this you would have to

  (define abc2652 "foo")

or something similar.
