[somehow OT] "undoing" manual tzdata compilation on a Mac

Hi Mario,

If you were able to compile the tzdata2009p on the mac os x, then you  
should be able to download an earlier version of tzdata and compile  
that to restore the mac. If you want to use the "original" files and  
don't have a mac than hasn't been updated, you can also download  
earlier updates or the original install software (depending on how far  
back you have to go) and then use a utility like Pacifist to extract  
the Argentina tz fille.

The mac does behave very wacky if the ICU database and the tzdata  
don't agree, different parts of the system reading from one or the  
other, and some from a combination of the two! If you would like to  
learn how to compile the mac ICU database I can point you to some  
links and share some of my experience (off list, unless others would  
consider it a suitable list topic). I do this myself to support Macs  
that are running XJ time, still not incorporated into official  

Please let me know where I might be able to help with more detailed
