Request #120 has been rejected by arcanis [1]: The package has a little bit out-of-dated PKGBUILD (for example, it has not package() function) and has incorrect sources list. If you will build this package you will get clean 2.49 version of blender.
I'll leave a comment in the package page. I don't see any reason to remove this package now. [1] https://aur.archlinux.org/account/arcanis/
