I did check the official Dreamhost Knowledge Base, and when I saw that GD Freetype was officially supported, sent a message through the support form to notify Dreamhost that it wasn’t working. I included pointers to the relevant messages in this board where the problem had been diagnosed, with the probable fix spelled out. I received a response within 24 hours that my request was being passed up to “level 2 technical support.”
That was three weeks ago. I never received another response, and Freetype still isn’t working. If that’s how Dreamhost interprets “fast and official,” I remain unimpressed.
