Unfortunately we are stuck here because the pypi website still has a
license that we cannot live with (it would have the effect of
assigning all work we upload to them).  They have said this is not
their intention, but declined to do anything about the actual wording.

After trying './configure --prefix=/tmp && make && make
install' I see
there's a disturbingly large number of problems/bugs in this area ...

The configure script only uses --prefix so far, but frequently
overrides it.  eg: OCaml scripts are always installed in
`ocamlc -where' and in the case above bash-completion scripts are
always installed in `pkg-config --variable=completionsdir bash-completion'.

I guess whether you think this is a bug or a feature depends on your
point of view ...

After using 'python sdist', can't you use the tarball (in
python/dist)
in order to create a venv directly?

Ah I see what is going on now. Interestingly I had this somehow
working with 1.27.49. I unfortunately did not keep detailed notes.

I think I will be able to install the python library in the venv using
the tarball. However, won't my liguestfs application require some of
the binaries installed as part of 'make install' for running? I am
trying to not have libguestfs installed outside of the venv.

Thanks,

Yes, it'll require only the following files and directory (using their
normal install location):

  /usr/lib64/libguestfs.so.0 -> libguestfs.so.0.<N>.0
  /usr/lib64/libguestfs.so.0.<N>.0
  /usr/lib64/guestfs/supermin.d

You can move these files/directory anywhere you want.  You will need
to set the environment variables `LD_LIBRARY_PATH' so that the shared
library is found, and `LIBGUESTFS_PATH' so that the supermin.d
directory can be found (you have to set LIBGUESTFS_PATH to the
*parent* directory of supermin.d).

If you look at the 'run' script which is created in the top level
source directory you can see some of the many environment variables
that may be set and how they are used.
