Hm. This only happens if you want to access a macro that is not in the 
current template but in a macro of another template used for render the 
current template. (Does this make sense?)

If the macro were in the current template you would be able to access it 
with 'template/macros/your_macro'.

I would simply create a folder called 'templates' (if you use 
portal_skins you'll don't need this) and create a template inside called 
'my_macros' and use the macros from this template.

With a 'templates' folder in the site root it would look like:

   metal:use-macro='here/templates/my_macros/macros/needful_thing'

Even simpler with CMF skins tool:

   metal:use-macro='here/my_macros/macros/needful_thing'

Does this work for you?
