There's Stratum Proxy. (there's some specific ones for specific pools, having trouble finding a general one for linux)
Basically, you connect the stratum proxy to the stratum server (the pool you want to connect to), then you point your getwork client (Reaper) to the stratum proxy instead of the pool... Basically it bounces the getwork connection to a stratum connection.
Once you start the stratum proxy, just connect using reaper at localhost:8332
