I just posted this method under the Thread (RefTeX: defining new label 
environment). Here it is again:
Enable display of labels in comments using reftex-label-menu-flags. Then 
just put a comment with the same label name somewhere near your actual 
label (the one reftex can't find).

I just did it for lstlistings like this:
%\label{lst:mylisting}
\begin{lstlisting}[caption={Some caption},label=lst:mylisting]
Some code
\end{lstlisting}

And as additional info specially for lstlisting, I also added a new 
environment using the reftex-label-alist customization buffer. Please 
search on the net for an explanation of how to do that. It is not that 
hard.

Cheers,
Martin
