Problem with X-Server after upgrading ncurses4

["Karl-Heinz Schulz" <karlheinz khschulz com>]

I don't if this is related to each other but I cannot start the X server
after upgrading the ncurses - this was the last change I did on the
system.

ncurses-5.2-12
XFree86-compat-libs-4.0.3-2
XFree86-75dpi-fonts-4.1.0-15
XFree86-devel-4.1.0-15
XFree86-xdm-4.1.0-15
XFree86-libs-4.1.0-15
XFree86-xfs-4.1.0-15
XFree86-4.1.0-15
kernel-2.4.9-21

I get the following error

execve failed for /etc/X11/X (errno 2)
giving up
xinit: Connection refuses (errno 111): unable to connect to X server
xinit: No such process (errno 3) : Server error.

What can cause this error.

TIA
