RubyInline <= 3.6.4 Compiler Error on Leopard

RubyInline versions prior to 3.6.5 may result in a CompilerError on OS X Leopard if Ruby was not compiled with the -undefined suppress flag. This flag will allow Ruby to ignore missing symbols.

You can fix this in RubyInline-3.6.X/lib/inline.rb by changing the line:

flags = @flags.join(' ')
to:

flags = @flags.join(' ') + ' -lruby'

RubyInline 3.6.5 fixes this problem but 3.6.5 does not work with the scRUBYt 3.4

To uninstall a particular version of RubyInline:

gem uninstall -v 3.6.5 RunyInLine

Output showing compiler error mentioned above:
