I thought some syntax highlighting on the code I post in this blog would be nice. So, when I found the SimpleHighlight plugin for Simplelog I was happy - now I wouldn’t even have to write any CSS for it:)

It’s not that simple, apparently.

I thought I’d post this in the hopes that someone recognizes the error. I’ve googled and poked around in the code and as far as I can tell it’s due to an incompatibility between the gems (namely textpow) and the oniguruma gem/c library.

For what it’s worth, I ended up following along with these instructions in my attempt to get it all working; I still get the same error.

Rails trace (the top few lines at least):
