sorry for my late reply I only got access to macOS10.9 today...

using 2.8.0_rc1, installation is fine, well done :)

now when linking my app I got this error:

-- 35/64: fixing up '/Users/nico/build/myApp.app/Contents/Frameworks/libX11.6.dylib'

it seems that install_name_tool does not like arm64.

is it something I need to deal with or something that you can deal with?

best regards,
