Xt library

[Andy Chan]

Dear Sir;

    I am new to FreeBSD. I am using FreeBSD 4.7 as a web server and I am
having a problem during the installation of ImageMagick 6.0 

    I have email to ImageMagick who told me that I need the Xt library. 
    
    /usr/X11R6/lib/libdps.so: undefined reference to `XtMalloc' 
    /usr/X11R6/lib/libdps.so: undefined reference to `XtSetEventDispatcher'

    Would you please kindly advise how to obtain these library? How may I
installed the libraries? I am sorry that I am new in BSD, please kindly
advise in details.

    Thanks for your kindly assistance.


Best Regards
Andy
