When trying to install xrootd in a virtualenv on Ubuntu 18.04.4 with python 3.7 via pyenv, the installation fails at the last step with `python3.7: command not found`.

The abridged error is:

```bash
$ pip install xrootd
.......
    -- Installing: /clusterfs4/rehlers/software/pyenv/versions/3.7.6/lib/python3.7/site-packages/pyxrootd/include/xrootd/private/XrdCl/XrdClFileSystemOperations.hh
    ./install.sh: line 35: cd: ../bindings/python: No such file or directory
    pyenv: python3.7: command not found

    The `python3.7' command exists in these Python versions:
      3.7.6

    Note: See 'pyenv help global' for tips on allowing both
          python2 and python3 to be found.

I added a symlink in `env/bin` from `python3` -> `python3.7`and then was able to install successfully.

Since I have to use pyenv on this system, I suspected that it might be the underlying issue, but looking at other systems which don't rely on pyenv, it looks like `python3.7` often isn't created in a virtualenv. So I don't think `pyenv` itself isn't the issue. Can it be less specific about the python version that it looks for? (ie. `python3` instead of `python3.7`).

Thanks!
