Doesn't look like so:

sandal:Desktop $ ruby -v
ruby 1.9.1 (2008-10-28 revision 19983) [i386-darwin9.4.0]
sandal:Desktop $ irb
>> __method__
=> :irb_binding
>> def foo
>>  __method__
>> end
=> nil
>> foo
=> :foo

Just keep in mind that Ruby 1.8.7 isn't a compatible Ruby 1.8 version.
 It's meant for um... I don't really know what, and if you want your
code to run on Ruby 1.8.6 (which is pretty important if you plan to
support 1.8 at all, IMO), it's not there:

sandal:prawn $ ruby -v
ruby 1.8.6 (2008-08-11 patchlevel 287) [i686-darwin9.4.0]
sandal:prawn $ irb
>> __method__
NameError: undefined local variable or method `__method__' for main:Object
	from (irb):1
