These errors are caused by sh not knowing what to do with the commands
(no command etc. found). The first one would be because it is looking
for a command that is that whole string (including arguments) rather
than the most likely intended "cleartool" to which the arguments will be
passed. This would indeed be caused by the double quotes.

I would start with creating some temporary variables to clean up the
code and ensure proper interpolation for debugging (make sure, in
particular, that nested quotes are properly escaped). Create one for
the command which optionally includes the path to the command (unless
it's a command which is expected to be in $PATH), and then a second
which has the arguments and then pass those variables to qx without
having to worry about quoting.
