It isn't that hard to compile it yourself, just grab the Wine 1.4 source and follow these instructions.
the latest stable release of wine is 1.5 not 1.4. maybe this release fixes the xcode compile problems mentioned?
you dont need to monkey with old versions of xcode to get GCC 4.2 either.
All 1.5.x releases are development releases, 1.4 is latest stable.
If you plan to run wine on OSX I suggest using Wineskin from www.doh123.com.
It has downloader for all recent wine and crossover binaries.
(from like 1.1.x to 1.5 including crossover 8 to 11.)
