Dinkum C/C++ Library

How can I check if I have the Dinkum C/C++ Library installed?

I was running QNX 6.2.1 NC and switching to PE. Using Installer to install
PE, I noticed I already has Dinkum installed. A QNX person suggested I
uninstall Dinkum and re-install it. I checked the box next to Dinkum and
selected the Uninstall button in Installer. After that Dinkum didn’t even
appear on the list in the Installer with the PE CD in the drive. Does
anyone know where I can get the Dinkum C/C++ Library that comes with PE that
I can use with Installer?
