I followed these instructions to build Kivy and other recipes in my virtualbox macOS Big Sur virtual machine. When I ran toolchain build python3 kivy or toolchain build kivy, I encountered the below error. Any advice? Many thanks.

Dear Taka (refer to Taka's post), thanks so much. This is the best answer I have ever seen for months. Your method saved the kivy on my MAC as well as my MAC VM. What happened was the version freetype-2.5.5 was moved to another sub folder on the savannah site. The newer version is 2.10.0. This is how I fixed my problem:
1. go to the init.py, update the version = "2.10.0". I can't just run toolchain build python3 kivy. This will throw error again.
2. I then have to go to the site, download the freetype-2.10.0.tar.bz2 file and save it in the .cache/ folder. This is how to go to the .cache folder in your MAC. Go to Finder -> Go -> Go to Folder -> type in /users/{username}/.cache

Your _init_.py file in freetype folder (For example, /Library/Frameworks/Python.framework/Versions/3.x/lib/python3.x/site-packages/kivy_ios/recipes/freetype/_init_.py) is referring to obsolete URL link, so you just need to edit the file and modify the "url = " like,
```
class FreetypeRecipe(Recipe):
    version = "2.5.5" 
    url =  "http://download.savannah.gnu.org/releases/freetype/freetype-{version}.tar.bz2" 
    library = "objs/.libs/libfreetype.a" 
    include_dir = ["include", ("builds/unix/ftconfig.h", "config/ftconfig.h")] 
    include_per_arch = True 
```

One way to solve this is to download the expected freetype package from here:

https://download-mirror.savannah.gnu.org/releases/freetype/freetype-old/freetype-2.5.5.tar.bz2

And then move it to the expected location. So in your case, you could run:

mv ~/Downloads/free-type-2.5.5.tar.bz2 ~/kivy-ios/.cache/freetype-freetype-2.5.5.tar.bz2

Then rerun build and it will get around the issue.

However, I think this error may indicate an environment issue. You should verify that you are using the correct version of Python3 for Kivy (which is currently 3.7.x). Check python3 --version.
