libxml2 installation/binding issue with Python 3.6.4

[Priest, Matt]

Hello,

I am not sure if this is the correct place to post an issue/question like this, but here goes...

I've successfully (?) installed Python 3.6.4 and libxml2, with the ultimate goal of installing GTK+ 3.22.0.
However, I'm running into this error:


python3
Python 3.6.4 (default, Feb  5 2018, 13:28:04)
[GCC 4.7.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import libxml2
Traceback (most recent call last):

    import libxml2mod
ImportError: /nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/lib/python3.6/site-packages/libxml2mod.so: undefined symbol: _PyVerify_fd


Here are the details on the version, cflags, and ldflags.
python3 --version ;

Anyhelp or hint would be appreciated...
