FYI in case someone else asks, there were missing links in
/usr/X11R6/lib64 (e.g. there was libXext.so.6 but not libXext.so), which
were the original cause of the problem. I don't know why these links are
missing (there probably is a good reason ?) but it sure creates problem
for people who want to compile their X11 apps :-(
