 First, even developers make mistakes.  If a developer is trying to build
 from scratch on a new machine, this ensures that all the required tools
 are in place.
 
 Second, the check is more than just for existence; it's also for the pathname.

 )
 
 Anyway, I found there's more or less the same bug report already at=20
 other/2529, so both should be closed then.
