Qt 5.1.1 and qmake conflict with Intel Compiler C++

[lgio]

Good evening to everyone.
This is my first post and perhaps my question is naif but I am at the beginning of my learning process of Qt.
I downloaded Qt 5.1.1 on my Mac OX.
With Qcreator no problem, qmake does his duty and everything works.
When I switch to the terminal the system does not recognize the comand qmake. If I enter in.Bash_profile export PATH indicating where to find qmake : /User/myhome/Qt/5.1.1/clang_64/bin this command conflicts with the Intel compiler C++ application that I installed on my Mac causing the full system lock (to fix things I do a restore of the entire hard disk; luckily I have a backup system).
I also did a system download Qt 4.8.5 and with this system qmake work without particular PATH. Unfortunately if I subsequently install Qt 5.1.1 qmake continues to point to the old version .
(restore of the system for cancel the Qt4.8 end is qmake etc..)
Where I'm wrong????????
Thank you.

try to use qmake with accurate path for qt 5.1. i use this way in linux:

/opt/qt5/bin/qmake

Thanks for the reply.
My problem is that I find qmake only in /Users/gl/Qt/5.1.1/clang_64/bin directory
And it is precisely with this directory that the system crashes.
Maybe something wrong with the export PATH.

Thanks
