    # ld --verbose | grep SEARCH_DIR | tr -s ' ;' \\012
    SEARCH_DIR("/usr/x86_64-pc-linux-gnu/lib64")
    SEARCH_DIR("/usr/lib64/binutils/x86_64-pc-linux-gnu/2.33.164")
    SEARCH_DIR("/usr/local/lib64")
    SEARCH_DIR("/lib64")
    SEARCH_DIR("/usr/lib64")
    SEARCH_DIR("/usr/x86_64-pc-linux-gnu/lib")
    SEARCH_DIR("/usr/lib64/binutils/x86_64-pc-linux-gnu/2.33.1")
    SEARCH_DIR("/usr/local/lib")
    SEARCH_DIR("/lib")
    SEARCH_DIR("/usr/lib")

So it looks like gps/packet.py is NOT using the system SEARCH_DIR.

The code does a lot of work to find the library, While this "just works"(tm):

    >>> import ctypes.util
    >>> ctypes.util.find_library("gpsdpacket")
    'libgpsdpacket.so.27'

Is there a good reason for gps/packet.py to work so hard?

Seems to me that the program should look for the lib:

        1) in GPSD_HOME
        2) in current directory
        3) using ctypes.util.find_library()

And, instead of looking for the exact lib version, just check the major
version after loading it.

Does that sound right?
