RSS: MM_XSLTransform error using GoDaddy

I'm having a big problem with running an RSS newsfeed on my site, using GoDaddy as a host. From what I'm reading, GoDaddy seems to have a big problem with this, but all of the fixes I've tried have resulted in different errors or no changes at all.
The code was working perfectly fine on my personal server, the error only showed up when I uploaded it to GoDaddy:
MM_XSLTransform error.
The server could not perform the XSL transformation because an XSLT processor for PHP could not be found. Contact your server administrator and ask them to install an XSLT processor for PHP.

I am running on a GoDaddy Linux account NOT a Windows hosing account.

I've put the code for all the related pages below with comments to separate the pages.

Note: this is my very first time putting RSS on a site, so please keep that in mind!

Well, I may not be able to help very much, but I could not help laughing out loud at "a Windows hosing account" - exactly my experience with Windows on GoDaddy!

;-)

Have you used phpinfo() to see if there are any XSL modules installed?  On my server, I have this:

'--with-xsl=/opt/xslt/'

XSL       enabled
libxslt Version       1.1.24
libxslt compiled against libxml Version       2.7.2
EXSLT       enabled
libexslt Version       1.1.24
