[Libreoffice] dragging masterbuild to another directory?

Hi*,

Sometimes I want to keep a build from master for some longer time.
So I copied the root/install folder to somewhere in my /home.
Initially that worked fine, could start it etc.

Now, few builds later, it will not start:
  error while loading shared libraries: libi18nisolang1gcc3.so: cannot 
open shared object file: No such file or directory

So either the copied build from master still points to some (simlinked) 
files, that have been changed in a later build.
Or ...?

Any advise if I want to keep a build for later testing/work?

Do not see it on:

Thanks,
