I have installed the QNX 6.5 base on a Linux platform and it works fine. I am trying to install 6.5 SP1 and the installer claims that the 6.5 baseline is not installed. How does the installer determine this?

My environment:

fc19> set |grep -i qnx
LD_LIBRARY_PATH=/usr/lib/xulrunner-1.9.2::/opt/qnx650/host/linux/x86/usr/lib
MAKEFLAGS=-I/opt/qnx650/target/qnx6/usr/include
OLDPWD=/home/users/staff/tpeterson/SVN-Todd/qnx/misc/spi-adc-32

QNX_JAVAHOME=/opt/qnx650/_jvm
QNX_TARGET=/opt/qnx650/target/qnx6
