OK, so the PATH issue must be a local problem to my machine. I have  
deleted the Environment.plist and re-created it from scratch using the  
plist editor. Still the same problem, I cannot modify the PATH. My  
default path is /sw/bin:/sw/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/ 
local/bin. If I append the required entries eg :/usr/local/Qt4.4 to  
the end of this string and then login, I get no change to the reported  
PATH using echo $PATH.

It is interesting when I enter >set, I get the following at the end of  
the output

........
_=/sw/bin:/sw/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin
__CF_USER_TEXT_ENCODING=0x1F5:0:0
osMajorVer=9
osMinorVer=5
perlversion=5.8.8
append_path ()
{
     if ! eval test -z "\"\${$1##*:$2:*}\"" -o -z "\"\${$1%%*:$2}\"" - 
o -z "\"\${$1##$2:*}\"" -o -z "\"\${$1##$2}\""; then
         eval "$1=\$$1:$2";
     fi
}
prepend_path ()
{
     if ! eval test -z "\"\${$1##*:$2:*}\"" -o -z "\"\${$1%%*:$2}\"" - 
o -z "\"\${$1##$2:*}\"" -o -z "\"\${$1##$2}\""; then
         eval "$1=$2:\$$1";
     fi
}

Things are going on here which go beyond our basic understanding. I do  
not know where this reported script append_path() is being derived,  
and I guess it is not an Apple derived function. That is a likely  
guess as to why I cannot modify the PATH.

It is fairly conclusive that the Evironment.plist cannot expand a  
$TEXT macro, but it seems you can simply overwrite PATH absolute. (But  
not on my machine).

Yes

This makes no difference whether the Environment.plist file is  
present, renamed or totally deleted.

BUT

Since I developed and ran the Apple scripts, I can now launch  
QtCreator without the script!!, and it is finding the System Qt and  
qmake each time now with no problem.

Very puzzling.  It could be that once Creator has found the System Qt,  
it then stores the absolute path which is being used subsequently in  
place of doing a getenv. Its all working now each time without the  
additional PATH settings.

I guess the only way to re-produce what I have experienced is to  
install the binary dmg on a machine with no developer code and no  
Creator history, and certainly on a machine that does not have my PATH  
issue!.

So thanks for your assistance, at least I am up and running now.
