can you link or post an example? This doesn't usually happen...

Thanks, i just checked it out real quick and found the problem. I attached a working tarball to this task.

The problem was the source line, it was like so:

source=("http://www.no-ip.com/client/linux/$pkgname-duc-linux.tar.gz"\
"noip2-conffile.diff" "noip2")

I changed it like so:
source=("http://www.no-ip.com/client/linux/$pkgname-duc-linux.tar.gz" \
"noip2-conffile.diff" "noip2")

Notice the only difference here is a space before the backslash, and this works fine. So for the time being, please modify your pkgbuild.

I admit that our parser probably should know this (we don't actually use bash to evaluate these), since bash doesn't choke on it, either should our parser. It's goin on the todo list ;)

Found our little issue here, not sure we can fix it because of the way we have the parser set up.

The little bugger's at line 194 of pkgsubmit.php, basically the problem here is that bash was evaluating it fine because there was whitespace on the next line, when I tried it in bash without whitespace on the next line, it behaved the same as the AUR did. The aur trims all the whitespace when it reads the line, but later on it goes using explode() along spaces to separate the sources.

We could possibly change around where some of the trimming is taking place... hmmm
