Mozilla not run !

I install mozilla (mozilla-ph-1.1-tar.gz from qnx download)
but not run:

unknown symbol: PhClipboardWrite
unknown symbol: PhClipboardRead

What is the problem ?

What version of QNX are you using?
If QNX 6.2.1, you might want to download/install the mozilla 1.5 from openqnx.com/Article212.html
