[CentOS] I need a package updated...

...Where do I go?

Hi please forgive me if I missed something obvious, but I've been reading and searching for a couple days to no avail.

I'm trying to get the latest cinelerra running on CentOS4.1 on a dual Xeon machine.

I need: cinelerra: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.4' not found (required by cinelerra) (x86_64)

and apparently the latest available is: libstdc++-3.4.3-22.1 (x86_64)

So, my question is, who maintains these packages? Is there a way to request an upgrade? It is easy to build your own? Or am I opening up a can of worms. If so, where can I turn to for info?

I have found libstdc++-3.4.4-2 but it's for ia64.

Thanks for any suggestions...
