I tried the patch that was suggested at the link that you mentioned. Now, various modules can be browsed. However, administration of those modules (as well as system administration) still does not work. In the case of the modules, whenever you click on their respective icons on the left in administration page, it says Selected module does not exist. For system administration, it does not save any changes you make.
Hopefully someone out there knows what's going on. I want to fix this before I decide whether to publish my site publicly.
