This worked for me as well. I then ran into the problem of not being  
able to find libruby.a (I'm really going from a stock Panther install,  
no recompiling ruby even for the static library), so I opened the  
project (framework/RubyCocoa.pbproj) in Xcode and made it link to the  
installed libruby.1.dylib instead. I'm still not sure if building it  
against the dynamic library will work, but I'm giving it a shot since  
Panther includes it.

Here's another issue I ran into:

src/objc/cocoa/rb_NSGraphics.m: In function `init_NSGraphics':
src/objc/cocoa/rb_NSGraphics.m:1483: error: `NSAlphaEqualToData'  
undeclared (first use in this function)
src/objc/cocoa/rb_NSGraphics.m:1484: error: `NSAlphaAlwaysOne'  
undeclared (first use in this function)

 From Mac OS X Panther Release Notes: Cocoa Application Framework  
(http://developer.apple.com/documentation/ReleaseNotes/Cocoa/ 
AppKit.html):

Obsolete Symbols
NSAlphaEqualToData and NSAlphaAlwaysOne (with values of 1 and 2,  
respectively) have been removed from NSGraphics.h as they have not been  
used since before 10.0.

I commented out the two appropriate lines in  
framework/src/objc/rb_NSGraphics.m, and the build continued.

Similarly, I found a number of constants in NSSavePanel that were  
deprecated and have been removed as of 10.3:

NSFileHandlingPanelImageButton
NSFileHandlingPanelTitleField
NSFileHandlingPanelBrowser
NSFileHandlingPanelForm
NSFileHandlingPanelHomeButton
NSFileHandlingPanelDiskButton
NSFileHandlingPanelDiskEjectButton

I commented these out in framework/src/objc/rb_NSSavePanel.m. After  
this, the build completed successfully, but it still doesn't appear to  
result in a working RubyCocoa:

kbullock:Source/ruby/rubycocoa-0.4.0% irb -r 'osx/cocoa'
objc: failed objc_getClass(NSObject) for NSServicesPasteboard->isa->isa
objc: please link appropriate classes in your program

This one I can't figure out. I can't even find what  
NSServicesPasteboard is on Apple's developer site. Any ideas here? Is  
anyone on the Japanese list working on this? (I unfortunately can't  
read Japanese.) Thanks for your help so far. If I can get this working,  
I'll submit a patch back.
