alevt's SPEC creates a directory at /usr/X11 to install it's
mini-alevt.xpm:
(line) 35 "install -m644 contrib/mini-alevt.xpm
$RPM_BUILD_ROOT/usr/X11/include/X11/pixmaps"
"%files
%defattr(-,root,root)
%doc CHANGELOG COPYRIGHT README alevt.lsm.in
%attr(0755,root,root) /usr/X11R6/bin/alevt
%attr(0755,root,root) /usr/bin/alevt-date

(line) 56%attr(0644,root,root) /usr/X11/include/X11/pixmaps/mini-alevt.xpm"

/usr/X11 as I understand is a dirctory once used prior to X11R6 but here
the way the writer intended is not to give backward compatibilty as in
aout-libs (which creates /usr/X11 as a symbolic link to /usr/X11R6) but it
appears as if whoever built this simply got his directory wrong and may
have intended to install this in /usr/X11R6/include....  .
This causes a scenerio in which if I'll install alevt and then aout-libs
I'll get this :

# rpm -i /blobs/real/alevt-1.4.9-2.i386.rpm
# rpm -i /blobs/real/aout-libs-1.4-14.i386.rpm
unpacking of archive failed on file /usr/X11: cpio: unlink 

Because the /usr/X11 is an existing directory and canont be used as the
link to /usr/X11R6.
All you need to do is check if the link exists in alevt spec or change that
pixmap's path.
