mesa fails to build due to external headers

[probono@…]

mesa fails to build on a ​PureDarwin 9 system. Is there a way to change this port in a way that doesn't rely on headers that are outside of MacPorts?

make[2]: Nothing to be done for `default'.
make[4]: `../../../lib/libGLU.dylib' is up to date.

Yes, don't use the (on by default) hw_render variant.

sudo port -v install mesa -hw_render

Thanks jeremyhu, with -hw_render it works.

Is it possible to add a "puredarwin" variant that sets -hw_render automatically? (Unfortunately I couldn't figure out from the docs how to achieve this.)
