X PixMap library not installed

[Marvin Stodolsky <stodolsk@erols.com>]

Even though I just:
   dpkg -i xpm4g_3.4k-5.deb, The X PixMap library
When pcmcia source is installed:

X Windows include files found.
X PixMap library not installed.
    If you wish to build the 'cardinfo' control panel, you need the XPM
    library and the X Windows include files.  See the HOWTO for details.
    *You can ignore this message if you are only rebuilding the
     PCMCIA modules.*
Configuration successful.

Anyone understand this?
