Installing php5-openssl on Amazon SUSE SE 11 SP3

I have a SUSE ES 11 SP3 Amazon EC2 instance and I need to install the php5-openssl package, but I'm getting in trouble when using "zypper install". I should have upgraded the insance infrastructure update (more details here), but I missed the deadline and I am now with a useless instance, because I can not install anything .

Whenever I use zypper install I got:

I tried to install each php5-openssl dependency, downloading each RPM and installing with rpm -i, but every time I resolve one dependency another appears. I also tried the suse forum (post here) but with no success until now.

So my questions are:

1. Is there some way to fix zypper repositories manually? Even if only to install the php5-openssl package.
2. Is there some way to use RPM to manage the dependencies for php5-openssl?
3. Is there another alternative to install php5-openssl in my suse instance?

in short:

1. you cannot fix these repositories; since they don't exist anymore (try browsing to http://sa-east-1-ec2-update.susecloud.net/).
2. rpm cannot look for dependencies because rpm does not use repositories (that's where zypper comes in). You can look for rpms on the internet, and then install the manually using rpm; but rpm won't locate the missing rpms.
3. Yes; as said in point 2; you can look for the rpms; download them and install them manually; or else you can even look for repositories that contain the rpms you want, and add that repository. However be careful with that; since those repositories probably aren't made for Amazon EC2. If you do this; try to find a repository as close as possible to suse 11 EC2...
