Here's the Safari 6.0.1 download URL: http://swcdn.apple.com/content/downloads/49/18/041-6773/wzbv8ta766d0ab5u260pcio6 riqiqwbo5k/Safari6.0.1Lion.pkg
Here's the way you can find it in the future via Terminal:
curl $(strings /System/Library/PrivateFrameworks/SoftwareUpdate.framework/SoftwareUpdate | grep http://swscan) | grep Safari6
To break it down, first you use strings to get the human readable strings from SoftwareUpdate.framework, then you pipe it to grep to just get the URL to the catalog file:
strings /System/Library/PrivateFrameworks/SoftwareUpdate.framework/SoftwareUpdate | grep http://swscan
On a Lion system this yields:
http://swscan.apple.com/content/catalogs/others/index-lion-snowleopard-leopard.m erged-1.sucatalog
So you can take that command and wrap it in $() so it's result is used for curl (the Unix command line URL getter), which will download the catalog, then that file is piped through grep to find Safari6, which interestingly yields 2 pacakges, the install and also a repair package!?

The .smd file has base64 encoded of chunks of html in various languages with the update description
The .pkm file is a package manifest, similar to the PackageInfo found inside a flat package, but with extra info about the frameworks and bundles to be downloaded
It seems the LionRepair package, will remove then restore a previous Safari version... which can also be accomplished with this hint: Restore previous Safari version from .SafariArchive.tar.gz - Mac OS X Hints
Anyway the short answer is in the first sentence of this post!Thanks for reading this far! 😀
"Give a man a package he'll be good until the next update, teach a man to fish the .sucatalog file and he'll be good for ... well, for a while, until apple changes it's update scheme" 😉
