# This routine makes sure that there is no previous installation of
# VirtualBox other than one installed using this install script or a
# compatible method.  We do this by checking for any of the VirtualBox
# applications in /usr/bin.  If these exist and are not symlinks into
# the installation directory, then we assume that they are from an
# incompatible previous installation.

## Helper routine: test for a particular VirtualBox binary and see if it
## is a link into a previous installation directory
##
## Arguments: 1) the binary to search for and
##            2) the installation directory (if any)
## Returns: false if an incompatible version was detected, true otherwise

## Main routine
##
## Argument: the directory where the previous installation should be
##           located.  If this is empty, then we will assume that any
##           installation of VirtualBox found is incompatible with this one.
## Returns: false if an incompatible installation was found, true otherwise
