You should read the README:
Do ./build-native.sh in the root directory of the project.
The minivpn part is obsolete. Early version used to ship a compiled version in the repository.
Question
I have downloaded the openvpn code from https://code.google.com/p/ics-openvpn/source/checkout and it compile succesfully but when I create a profile and try to connect it .. it will give me an error "Error writing minivpn binary "
the readme file says Optional: Copy minivpn from lib/ to assets (if you want your own compiled version)
but I havent found any minivpn or lib like this in the package please let me know if some has worked on it
