Natalia's workaround reminded me of something I added to the
installation notes for the Aviage products. Could it be the same
problem? Here's what the Aviage notes say:

Coexistence on Linux (Ref# 73411)

It's possible to have more than one version of the QNX Software
Development Platform installed on your system, and it's possible to
install QNX Aviage products for each version of QNX SDP. However, due to
a limitation in InstallShield, you have to take some extra steps
installing QNX Aviage products on Linux hosts.

When two or more versions of QNX SDP coexist on Linux, you use the
following command to switch between configurations to set up the
environment in the current shell:

eval `qconfig -n "installation_name_as_displayed_by_qconfig" -e`

When you launch any of the QNX Aviage installers from that shell, the
environment picked up by InstallShield is whatever version of QNX SDP
you installed last, not the version that you selected using the command
above.

For example, if you install QNX SDP 6.4.0, then QNX 6.4.1, and you then
choose 6.4.0 and try to install a QNX Aviage product on the 6.4.0
baseline, the installation location displayed by the installers isn't
/opt/qnx640 (as expected), but /opt/qnx641.

In order to work around this issue, you must edit /etc/profile.

Note: 	We recommend that you save a copy of this file before you edit
it.

Edit /etc/profile, and find the section that looks like this:

# Begin INSTALLSHIELD Environment Variable Section
# Do not edit this section manually.
# var 0 QNX_CONFIGURATION=/etc/qnx
QNX_CONFIGURATION=/etc/qnx
export QNX_CONFIGURATION

# var 0 QNX_TARGET=/opt/qnx641/target/qnx6
QNX_TARGET=/opt/qnx641/target/qnx6
export QNX_TARGET

# var 0 MAKEFLAGS=-I/opt/qnx641/target/qnx6/usr/include
MAKEFLAGS=-I/opt/qnx641/target/qnx6/usr/include
export MAKEFLAGS

# var 1 :
PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin
:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/etc/qnx/bin:/root/bin:/et
c/qnx/bin:/root/bin:/opt/qnx641/host/linux/x86/usr/bin:/etc/qnx/bin
PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin
:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/etc/qnx/bin:/root/bin:/et
c/qnx/bin:/root/bin:/opt/qnx641/host/linux/x86/usr/bin:/etc/qnx/bin
export PATH

# var 0 QNX_HOST=/opt/qnx641/host/linux/x86
QNX_HOST=/opt/qnx641/host/linux/x86
export QNX_HOST

# var 1 : LD_LIBRARY_PATH=echo
$LD_LIBRARY_PATH:/opt/qnx640/host/linux/x86/usr/lib:/opt/qnx641/host/lin
ux/x86/usr/lib
if [ -z "echo $LD_LIBRARY_PATH" ]
then
LD_LIBRARY_PATH=/opt/qnx640/host/linux/x86/usr/lib:/opt/qnx641/host/linu
x/x86/usr/lib
else
LD_LIBRARY_PATH=echo
$LD_LIBRARY_PATH:/opt/qnx640/host/linux/x86/usr/lib:/opt/qnx641/host/lin
ux/x86/usr/lib
fi
export LD_LIBRARY_PATH

# var 0 QNX_JAVAHOME=/opt/qnx641/_jvm
QNX_JAVAHOME=/opt/qnx641/_jvm
export QNX_JAVAHOME

# End INSTALLSHIELD Environment Variable Section

Ignore the "Do not edit this section manually" instruction, and change
(in this example) all occurrences of the 6.4.1 installation directory
(/opt/qnx641) into the directory where you installed 6.4.0. Save your
changes, and then continue with the installation.

Once you've installed the QNX Aviage product, you might want to restore
/etc/profile from the backup that you made.
