Sorry to say, but it makes you dumb/stupid.
There is really nothing smart about juggling with downloading the correct DLL versions etc. yourself.
E.g., I installed OpenOffice 4 and installed all the needed DLLs. I checked them with PMDLL.
There didn't seem to be any dependencies, which weren't resolved. OO would start and then ... nothing.
After I installed the Package Manager and downloaded the needed packages, finally, I could use OO.
BTW, yum/rpm installs a lot more than just some DLLs.
If you ask me, I'd rather be stupid for letting some tool(!) install the DLLs and porting apps than wasting my time juggling the DLL installs.
