QNX 6.2NC +xf4.2 +Qt3

Hi everybody !
I have little time to test 6.2NC and resolve, I hope, my SMP lockup problem.
So I'm searching the good way to make Qt3 works with QNX 6.2NC. 

Here is my test :
1- install QNX 6.2 NC from CDROM ;
2- install packages from 6.2NC CDROM ;
3- install XFree4.2 and Qt3 binaries from openqnx site ;

	In this state, if I try to start designer under XPhoton (with a big P) or 
compile a Qt3 prog, I get this message :
	unable to find libphrenderGL.so and this file doesn't exist on the HD. 

So, I install Photon 3D runtime and devel packages from third party software 
CD.
	re-test wih designer and get this result 
		unresolved symbols : glXQueryServerString
			"	    : glXQueryExtension
		...

What's wrong with my install ? (I'm disoriented with problem aboutl ib 
between 6.1 and 6.2).

Thanks
