Just see how many comments are there in the last two links. Only two comments and those are complaints about invalid links. I hope you can see it before taking someone's side who questions others ability.
I already tried downloading the package manually from Cisco official page and try building but it ends up only in errors.
If you expect only an Arch Pro to work on your AUR stuff, then I have nothing to say. Let them pick all these pieces from diff location and try to build it.

I expect no more talk about the same. Thank you.
