Building py-libxml2 fails (Ubuntu 22.04, unprivileged pkgsrc), because of the use of wrong headers (?) #150

On Ubuntu 22.04, the installation crashes when the libxml2-dev package is installed. Removing it makes the installation succeed. I noticed that in the former case the compilation log contains the following lines:

While in the latter case it contains

As you can see, in the former case it contains -I/usr/include/libxml2 and it presumabely makes it fail. I have the line PREFER_PKGSRC=yes in my mk.conf.

@algor512, which commit is that, please?

@sskras sorry, I forgot to indicate that: I use the current trunk, so the commit c8e90121ca7b250d38fe34530797c4ac45d1dc14.
