It seems as though the BridgeSupport definition of CGContextRef is missing. At
this point, I'm not sure where it should be coming from, documentation
indicates ApplicationServices.framework, but it's not in there.
On Mountain Lion, we have a similar problem with some CoreGraphics definitions
missing from the bridge support file it should be in. In that case, it turned
out that Apple has two CoreGraphics.frameworks and only one shows up in the
dependency chain. I did a quick ack through the /System/Library/Frameworks and
didn't see a definition for CGContextRef, so I'm not sure if I missed it or if
it is somewhere else now.
Bridge support on stuff that is changing seems to be a bit iffy on Mountain
Lion. The bridge support source used to be on macosforge.org, but Apple seems
to have taken it down (the bridge support developer left Apple and moved to
Belgium). The long term strategy will be to bring the bridge support stuff into
MacRuby itself; however, someone who has the source code will have to post it
somewhere for us first.
Sorry that I don't have better news; Objective-C for this segment might be your
only option. :(
