checking if module mako in python is installed... No module named mako
configure: error: mako 0.3.4 or later is required.

Since mesa still requires mako for python-2.7 (WTF?) but doesn't specify so. Please add [${PYTHON_USEDEP}] to the dependency.

Thanks for the report.

I must be doing something obviously wrong... but I'm not sure what:

> >=dev-python/mako-0.7.3[${PYTHON_USEDEP}]

yields:

> Error(s) in metadata for 'media-libs/mesa-10.5.0_rc1':
>  DEPEND: Invalid atom (Invalid use dep: ''), token 163

Looks like PYTHON_USEDEP is undefined, but we're inheriting python-any-r1 which seems to define it.

I see other packages like libxcb use python_gen_any_dep, but I don't understand why. In any case,

> $(python_gen_any_dep ">=dev-python/mako-0.7.3[\${PYTHON_USEDEP}]")

seems to fix it. Is that what I should do?

Global-scope won't work for python-any-r1 since it does not define any flags in IUSE. And yes, python_gen_any_dep is the correct solution.
