gtk 1.2.10 install problem

[Shrisha Rao <shrao nyx net>]

When I try to install gtk 1.2.10 on Mandrake-Linux 8.0 (kernel 2.4.3);
this happens during ./configure:

[...]
checking for X... no
configure: error:
*** X libraries or include files not found. Check 'config.log' for
*** more details.

`config.log' has the following rather un-enlightening information on the
subject:

configure:4687: gcc -o conftest -g -O2 -Wall   conftest.c -lXt   1>&5
configure: In function `main':
configure:4683: warning: implicit declaration of function `XtMalloc'
/usr/bin/ld: cannot find -lXt
collect2: ld returned 1 exit status
configure: failed program was:
#line 4680 "configure"
#include "confdefs.h"

int main() {
XtMalloc()
; return 0; }

Any ideas what's happening, and how to fix the problem?  TIA.
