The PREFIX option when you compile Wine determines where it installs. (It should default to /usr/local) When running Wine, you want to set the WINEPREFIX environment variable (It is a run-time option, not compile time) (Yu can export it to set it for all processes started from that shell, or you can use env / prefix it to the command to set it for every involkation) e.g. WINEPREFIX=~/.wine wine winecfg # Gets primary wineprefix's winecfg WINEPREFIX=~/.wine-cssource ~/.wine-1.3.6/bin/wine winecfg # Gets ~/.wine-cssource's winecfg using Wine binary from the compile wine 1.3.6 (reinstalling it into /usr/local might make more sense...)
