11:07 nuriaion: has somebody tried dr racket on OS X Lion?
11:08 stamourv: sstrickl installed Lion yesterday, and I haven't heard him report any problems.
11:09 nuriaion: ok. then it's probably me who made an error
11:09 nuriaion: will try again
11:10 stamourv: Back when Lion was only available as a developer preview, some users reported issues on the mailing list, but I believe they have been fixed since.
11:10 stamourv: Which version of Racket are you trying with?
11:11 nuriaion: 5.1.1 for OS X (Intel i386)
11:12 eli: nuriaion: How do you know if some OSX machine is a lion?
11:13 stamourv: nuriaion: Could you try a nightly build?
11:13 stamourv: http://pre.racket-lang.org/release/installers/
11:13 nuriaion: i can try
11:13 stamourv: Great.
11:14 stamourv: I suspect most of the issues have been fixed since 5.1.1.
11:14 nuriaion: to install i download the .dmg, copy the folder to the harddisk and start DrRacket.app. Or is there some aditional step?
11:14 stamourv: The fixes should be included in 5.1.2, which is coming pretty soon.
11:14 stamourv: The install process should be the same as with a release build.
11:14 eli: nuriaion: Specifically, the 64 bit build is on a machine which I *think* is a lion.
11:15 nuriaion: @eli if the machine grows yellow fur.
