Yes, we need to do this, it's just things are a bit in flux at the moment.

But, you should now be able to build the latest ODB compiler (and libodb*
libraries) pretty much automatically (and without CLI) from our staging
repository:

https://stage.build2.org/?q=odb

Here are the steps:

1. Build the latest staged build2 toolchain by following the installation
   instructions found here:

   https://build2.org/install.xhtml

   BUT: using the install scripts from here:

   https://stage.build2.org/0/

2. Once you have the build2 toolchain, to build the ODB compiler:

   $ bpkg create -d odb-build cc config.cxx=g++
   $ cd odb-build
   $ bpkg build odb at https://stage.build2.org/1

   To install:

   $ bpkg install \
     config.install.root=/usr/local \
     config.install.sudo=sudo \
     odb

   See "Package Consumption" for more information:

   https://build2.org/build2-toolchain/doc/build2-toolchain-intro.xhtml#guide-consume-pkg

Let me know if there are any issues.
