Hi Michael,
I am not an expert with configure but here's my take on your problem ...
If you have a look in the configure script and search for that error
message you'll find some code that looks like this
-----------------------------------
if test "x$XTversion" = "x" ; then
echo $ac_n "checking for Xt Revision Number 5""... $ac_c" 1>&6
echo "configure:4790: checking for Xt Revision Number 5" >&5
cat > conftest.$ac_ext <<EOF
#line 4792 "configure"
#include "confdefs.h"
#include <X11/Intrinsic.h>
int main() {
#if XtSpecificationRelease < 5
fail;
#endif
; return 0; }
EOF
-----------------------------------------
What this seems to be doing is to create a small c program which is then
compiled and run to do the test.
It may look horrible but basically it is just testing the value of
XtSpecificationRelease which is found in the file X11/Intrinsic.h
So, if you can find that file (try "locate Intrinsic.h") you can check
the value yourself (try "grep XtSpecificationRelease `locate
Intrinsic.h`" note the back-quotes and don't type the double-quotes).
You'll probably find a line like
#define XtSpecificationRelease 6
which is fine.
If this all checks out then your problem is most likely related to where
X11 is installed on your system and you need to use the --x-includes and
--x-libraries options when you run configure. They, and many others, are
described in the Install file.
You probably should do a "make clean" and a "make distclean" to get rid
of any mis-configured files which have been created previously.
Hope that helps.
Have Fun,
John L.
