I gladly did it for you in this case.
For macOS 10.6 (according to comment), latest LibreOffice version supporting the platform is 4.3. You may download it from download archive.
Libreoffice 4.3.6.2 runs happily on my MBP 17" OSX 10.6.8. LibreOffice auto update function says there are no more updates.
I see there is a 4.3.7.2 but I haven’t tried it, and presume it is incompatible with 10.6.8.
