I have a Rails app that uses the validates_captcha plugin. The plugin uses RMagick to generate CAPTCHA images. When deployed to HMS, I get the error:

"Can't measure text. Are the fonts installed? Is the FreeType library installed?"

I'm guessing this means that ImageMagick on HMS isn't configured with certain font options. How can I verify and/or fix this?

Unfortunately, your best bet would be to contact support. Josh or Paul should know about it. Personally, my captcha system is proprietary, and maybe i'm doing something differently.
