Install fails with two Python exceptions

[monotonee]

The first exception is raised when I, on a Linux-based system using Python 3.9, attempt to install fluxclient without PCL extensions:

Traceback (most recent call last):
      File "${HOME}/src/third-party/fluxclient/setup_utils.py", line 180, in create_pcl_extentions
        raise RuntimeError("Can not locate pcl includes.")
    RuntimeError: Can not locate pcl includes.
    Traceback (most recent call last):
      File "${HOME}/src/third-party/fluxclient/setup_utils.py", line 180, in create_pcl_extentions
        raise RuntimeError("Can not locate pcl includes.")
    RuntimeError: Can not locate pcl includes.
    
    During handling of the above exception, another exception occurred:
    
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "${HOME}/src/third-party/fluxclient/setup.py", line 10, in <module>
        ext_modules += setup_utils.create_pcl_extentions()
      File "${HOME}/src/third-party/fluxclient/setup_utils.py", line 241, in create_pcl_extentions
        sys.stderr("""\033[93m
    TypeError: '_io.TextIOWrapper' object is not callable

When the former code error is corrected, the following exception is raised when execution is allowed to continue:

Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "${HOME}/src/third-party/fluxclient/setup.py", line 38, in <module>

      File "${HOME}/src/third-party/fluxclient/setup_utils.py", line 91, in get_packages
        return [name
      File "${HOME}/src/third-party/fluxclient/setup_utils.py", line 91, in <listcomp>
        return [name
      File "/usr/lib/python3.9/pkgutil.py", line 88, in walk_packages
        for info in iter_modules(path, prefix):
      File "/usr/lib/python3.9/pkgutil.py", line 124, in iter_modules
        raise ValueError("path must be None or list of paths to look for "
    ValueError: path must be None or list of paths to look for modules in

In setup_utils.py, find the following lines:

if has_package("pcl_common-1.8"):
    include_dirs += [locate_includes("pcl_common-1.8")]
    library_dirs += [locate_includes("pcl_common-1.8")]

and change the 1.8 to the exact version of libpcl-dev you have installed (it would very likely be 1.9)

and then find the following lines:

def get_packages():    
    return [name            
                 for _, name, ispkg in walk_packages(".")            
                 if name.startswith("fluxclient") and ispkg]

and change the string "." to a list ["."]
