Oh, I already did so. Else my programs would not run. I make my own sources/qt451/bin dir and put symlinks there to all needed tools. Yes, ok... that indeed is a possibility. I just thought I may misunderstood something or missed a special tool to "convert" the SDK stuff back to the old fashion.

Well, then I have to checkin my bash script. Cool, then I now can test my brand new book "programming the shell" Well, let's see... (book is in the office, I just scribble down some thoughts, so no code quotes)
#!/bin/bash
dir = $1
# dont know how to check/handle params
test [ -d $dir | die "Dir already exist" ]
# or was "die" from perl?
test [ -d $dir/bin | mkdir $dir/bin ]
# or similar
for( $i in ["qmake" "assisant" "linguist" ]
ln -sf /Develop/Tools/Qt/$i.app/dontremember/MacOS/$i $dir/bin/$i

Something like that, I'll have it next week Anyway, it becomes deep OT
