Deployment to (mt) GridServer 99%...help me with the 1%

So my app is working great it seems. The deployment works great, all
the data is migrated over from my old host, etc.

One thing, when I hit the homepage, I get a 500 error and I believe it
has to do with RedCloth. Any page on the site where I use the
textilize() function, I get the error page. I installed and unpacked
RedCloth 3.0.4 into my /vendor/plugins/ directory and re-deployed to
no avail.

Is there anything I am missing here? The errors in the production log
are kinda cryptic.

I can show someone the URLs in a private convo (dont want to post my
media temple customer number here)
