Here's the problem:

  configure:14640: gcc -c  -g3 -O2 -isystem /usr/include/librsvg-2.0 -isystem 
/usr/include/glib-2.0 -isystem /usr/lib64/glib-2.0/include -isystem 
/usr/include/libmount -isystem /usr/include/blkid -isystem 
/usr/include/gdk-pixbuf-2.0 -pthread -isystem /usr/include/cairo -isystem 
/usr/include/pixman-1 -isystem /usr/include/freetype2 -isystem 
/usr/include/libpng16      conftest.c >&5
  conftest.c:119:10: fatal error: X11/Intrinsic.h: No such file or directory
    119 | #include <X11/Intrinsic.h>
        |          ^~~~~~~~~~~~~~~~~
  compilation terminated.

Your X11 headers seem to be in bad shape.  Maybe you need to
re-install some development package(s)?
