a problem about Vi

[Frank]

Hi, all,

When I execute vi in a shell, a error appears like this:

vim: error while loading shared libraries: libXinerama.so.1: cannot open 
shared object file: No such file or directory

When I  locate libXinerama.so.1, I can not locate it

And then I locate Xinerama.  It told that there is a file named as 
Xinerama.a in  /usr/X11R6/lib/libXinerama.a

So, what I can do now?

Thanks everybody!

Frank
