Comment 1 for bug 604275

Hi, Brooks!

Thanks for the bug report. It's funny, I went to Google that error, and the first result was a blog post by Chris Oliver (the project leader): http://excid3.com/blog/2010/06/unable-to-open-file-unknown-opcode/

It appears that this is a problem has surfaced before on 64-bit Linux systems. Is that what you're running Keryx on when you get this error?
