Comment(by neteler):

 Replying to [comment:34 wenzeslaus]:
 > `r.basin` is using function `error()` which is something different than
 function `fatal()`. `error()` just prints the message and continues,
 `fatal()` actually exits and raises. So, the behavior is correct according
 to implementation and is the same before r62566 and after r62705.

 Ah, I overlooked this difference. r.basin fixed in r62708, now it exits as
 expected in case a dependency wasn't installed yet.
