Problems when Installing asterisk 1.8?

[foxatlarge]

I followed the instructions below and installed Arch Linux ARM.
http://archlinuxarm.org/platforms/armv6 ... provideov3

Then I continue to install asterisk according to the below link:
https://wiki.archlinux.org/index.php/AUR

1) wget http://downloads.asterisk.org/pub/telep ... ent.tar.gz
2) cd [~/builds]
tar -xvzf asterisk-1.8-current.tar.gz
3)nano PKGBUILD
nano asterisk-1.8.8.2.install
4) makepkg -s
------------------------------------------
Here I got error message:
==> ERROR: Running makepkg as root is a BAD idea and can cause permanent, catastrophic damage to your system. If you wish to run as root, please use the --asroot option.

When I type:
makepkg --asroot

I got error message:
==> ERROR: pkgname is not allowed to be empty.
==> ERROR: pkgrel is not allowed to be empty.
==> ERROR: pkgver is not allowed to be empty.
==> ERROR: is not available for the 'arm' architecture.
Note that many packages may need a line added to their PKGBUILD
such as arch-('arm')
----------------------------------------------------------------------

Anyone can give me some hint to solve the problem?

Probably it wanted this
makepkg -Acs --asroot
But why do that, asterisk-1.8.2.3 is built already
Update first
pacman -S asterisk

Then after installation, can I type "asterisk" to run the program?

$this->bbcode_second_pass_quote('pepedog', 'P')robably it wanted this
makepkg -Acs --asroot
But why do that, asterisk-1.8.2.3 is built already
Update first
pacman -S asterisk

[pepedog]

rc.d start asterisk
to start
or to debug
asterisk -cvvv
