Um, first off, the $2 would reference the text matching the *second* set
of parens in the rewriterule pattern, but you don't seem to *have* a
second pair of parens in your rewriterule pattern.

Second, if you change the $2 to $1 it will match, and append onto your
new URL, either the "bin" or "cgi-bin" string, whichever matched in the
old url.  This doesn't appear to be what you were going for.  To
backreference the first parenthetic part from a rewrite condition
pattern on an earlier line, try using %1 instead.

Well, there's just the Apache docs themselves, for the mod_rewrite

and (linked from the bottom of that) the "URL Rewriting Guide":

which is a *bit* more tutorial-like, but reported by many to still
require a voodoo doctorate to understand it.
