UNIX cache problem?

So I worked out a script for Mac OSX from an existing script. This script checks the versionnumber of a plugin and a package. If the plugin version is different from the package it has to update the plugin. The script works fine but the final check fails.

Here is my script:

Code:

#compare version numbers
installedversion=`/usr/bin/defaults read /location/plugin.plugin/Contents/Info CFBundleShortVersionString`
newestversion=`/usr/bin/defaults read /otherlocation/plugin.pkg/Contents/Info CFBundleShortVersionString`
if [ "${installedversion}" != "${newestversion}" ]; then
installer -pkg /otherlocation/plugin.pkg -target /
# check if the installation succeeded
newlyinstalledversion=`/usr/bin/defaults read /location/plugin.plugin/Contents/Info CFBundleShortVersionString`
    if [ "${newestversion}" = "${newlyinstalledversion}" ]; then
        /bin/echo "`date`: SUCCESS: ${newlyinstalledversion} installed..." >> ${logfile}
        else
        /bin/echo "`date`: ERROR: update unsuccessful, version remains at {installedversion}." >> ${logfile}
    fi
fi

So lets say the installedversion is OLD and the newestversion is NEW.
It keeps saying ERROR. If I manually check the version number it's updated to version NEW.
If I add a line to the script to echo the ${newlyinstalledversion} to the log file it says OLD.
I tried to add 10 or 20 seconds 'sleep' after the installer command but that didn't help.
Is this a cache problem?

build-lives-rfx-plugin-multi(1) 			      General Commands Manual				   build-lives-rfx-plugin-multi(1)

NAME

       build-lives-rfx-plugin-multi - builds rendered effects for LiVES

SYNOPSIS

       build-lives-rfx-plugin-multi type [scripts_dir exec_dir] [build_bindir]

DESCRIPTION

       This  perl  script  builds  rendered  effects (RFX) plugins for LiVES. If scripts_dir is not defined then type is used to locate the plugin
       scripts directory and output directory. Type can be builtin (the default), custom,
	test, or builtinx. The type builtinx forces scripts_dir and exec_dir to be read from parameters and is used during LiVES install,  and	is
       the only type which should be used if scripts_dir is specified.

       Each  plugin script in input directory is scanned to find its language code. The script is then passed to the script compiler for that lan-
       guage.  The directory location of the script_compiler may be specified by the build_bindir parameter (as is the case during LiVES installa-
       tion0; otherwise the user's $PATH will be searched.

       Return values the script returns the following values

       0 - success 1 - the "type" parameter was not defined, or set to an invalid value 3 - the builder for a plugin script was not found
