------- Additional Comments from Tuukka Hastrup <Tuukka.Hastrup at iki.fi>
Actually the initial patch prints an error message for the first command that
can't be executed, followed by the message about the list of all required
commands. 

But why not take one more step towards usability indeed. I've updated the patch
according to the feedback, requesting a new review. Example output:

~/svn/WebKit$ WebKitTools/Scripts/build-webkit --gdk
Can't exec "flex": No such file or directory at
/home/tuukka/svn/WebKit/WebKitTools/Scripts/webkitdirs.pm line 497.
Can't exec "gperf": No such file or directory at
/home/tuukka/svn/WebKit/WebKitTools/Scripts/webkitdirs.pm line 497.
flex, gperf missing but required to build WebKit.
~/svn/WebKit$
