Thanks, that comes in handy! But the results only show what I already knew. But I got a little further. I thought maybe it just needs more time. So I put 40 seconds after the installer command and now it did say version NEW. Then I changed it to 20 seconds and again version NEW. But when I changed it to 10 seconds it said version OLD.
The strange thing is that when I look at the actual .plugin in Finder during the installation, the version almost directly changes to NEW. After that the sleep command runs for 10 seconds. After the ten seconds it still reads out version OLD.

So somehow it does cache the information somewhere...

Oke,

So I found another workaround, not a real solution. The plugin has besides an Info.plist also a Version.plist. So I've done some testing.

If I use the CFBundleShortVersionString from the Version.plist for the installedversion as well as the newlyinstalledversion I get the same problem. But If I use the Version.plist for the installedversion and the Info.plist for the newlyinstalledversion then it works properly. Even without the 10 seconds sleep.

Since this script can be used for more software other than this plugin this is not a real solution. Because not all plugins or apps have the version.plist.

I also tried unset installedversion but that didn't help either...

I also found something in another post that maybe will help finding a solution:

When you run a script or program, it gets a copy of your current environment. But the copy is unconnected. Change the child and the parent remains the same, and vice versa.

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

NAME

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

SYNOPSIS

       build-lives-rfx-plugin script_name [plugin_dir] -get section file

DESCRIPTION

       This perl script is used by LiVES to compile an RFX (rendered effect) plugin for LiVES. It is generally called from build-lives-rfx-plugin-
       multi for a script which has a language code representing LiVES-perl. The script_name must be  the  full  (absolute)  path  to  the  plugin
       script,	and  plugin_dir  can  be  used to specify the output directory where the compiled plugin should be generated. If plugin_dir is not
       defined then /tmp is assumed.

       The second variant with -get is used to print out a script section from a plugin script to stdout. It is generally only used internally	by
       LiVES.

       Return values The script returns the following values

       0 - success 1 - the value of a trigger was greater than the number of parameters 2 - a value could not be read from the script file 3 - the
       language code of the plugin script was not equivalent to LiVES-perl 4 - the API version level of the plugin script  was	invalid  5  -  the
       <define> section was missing from the plugin script
