Mac installation issue with .profile

[jcr]

Hello,
I am pretty new with the mac, so the question might be dumb.. but here it goes.
I have successfully installed qt 4.1.4.
I found the .profile file using the terminal in /Users/<yourUsername>/
and the .profile file now contains:

# Your previous .profile  (if any) is saved as .profile.dpsaved
# Setting the path for DarwinPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
PATH=/usr/local/Trolltech/Qt-4.1.4/bin:$PATH
export PATH

# Your previous .profile  (if any) is saved as .profile.dpsaved
# Setting the path for DarwinPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
PATH=/usr/local/Trolltech/Qt-4.1.4/bin:$PATH
export PATH

To copy to clipboard, switch view to plain text mode 

when I type qmake in the terminal, I am getting:
-bash: qmake: command not found
when I go to the directory /usr/local/Trolltech/Qt-4.1.4/bin and I type qmake there same answer... I must be missing something obvious

Thanks helping me out.
