Error Installin XBase

[Daniel.Farmer@srs.gov]

     When i run dpkg on the xbase_3_3_2_3-2.deb file i receive the 
     following error:
     
     can not create symbolic link '/usr/X11R6/lib/X11/doc' to 
     '../../../doc/X11': no such file or directory
     
     
     Any one have any guesses.  I've installed xlib6g_3_3_2_3-2.deb and 
     other required packages O.K..  
     
     Thanks for any help!
