Built from git tag v8.0, using make PREFIX=/usr/local.

Was able to get it to build like so:

git clone https://github.com/AltraMayor/f3
cd f3
git checkout v8.0
git clone https://github.com/xhebox/libuargp
make -C libuargp prefix=/usr/local
make -C libuargp prefix=/usr/local includedir= libdir= DESTDIR=$PWD install
make PREFIX=/usr/local

sometimes, that is. i can't actually get this build to work in the package file.
