[lxml] Build problems on Python 3.11

May 31, 2022

      Hi,

while I don't see this locally, I'm getting problems on my CI with the 
Docker Image:

```
      Compile failed: command '/usr/bin/gcc' failed with exit code 1
       cc -I/usr/include/libxml2 -I/usr/include/libxml2 -c 
/tmp/xmlXPathInitw7u6s7rr.c -o tmp/xmlXPathInitw7u6s7rr.o
       cc tmp/xmlXPathInitw7u6s7rr.o -lxml2 -o a.out
       error: command '/usr/bin/gcc' failed with exit code 1
       [end of output]

   note: This error originates from a subprocess, and is likely not a 
problem with pip.
error: legacy-install-failure
× Encountered error while trying to install package.
╰─> lxml
```

I'm wondering if there is anything that can be done about this? 
Presumably inform the maintainer?

Charlie
