Question regarding Hydra build target "x86_64-darwin"

[Assaf Gordon]

Hello,

A small question regarding the Hydra/NixOS target "x86_64-darwin" - is that a 
standard Apple Mac OS X system ?

One hint I found in the logs is the "configure" detecting the host as 
"x86_64-apple-darwin10.2.0" - so would it be correct to assume this is a Mac OS X version 10.6.2 
"Snow Leopard" ?

Or in a more practical terms - if my package passes a build on this hydra 
target - is it reasonable to assume it will compile correctly on Mac OS X 10.6 ?

Or, is it a variant of PureDarwin/OpenDarwin, and as such should not indicate 
anything about Mac OS X ?

Thank you,
 - Assaf
