Subject: compiling ruby/tk on 64 bit Redhat?

HI All:

  I"m wondering if anyone has successfully done this.  I'm trying to
build 1.8.5 with ruby/tk extension.  It seems the extconf.rb can't find
XOpen Display.  I hand tweaked the makefiles with values from Makefiles
that I've successfully built on other unix'es and built, but I get the
following sort of error

>> require 'tk'
root = Tk=> true
>> root = TkRoot.new
RuntimeError: hash modified
        from /home/users/fchang/local_linux/lib/ruby/1.8/tk.rb:3339:in
`_symbolkey2str'
        from /home/users/fchang/local_linux/lib/ruby/1.8/tk.rb:3339:in
`initialize'
        from
/home/users/fchang/local_linux/lib/ruby/1.8/tk/root.rb:36:in `new'
        from
/home/users/fchang/local_linux/lib/ruby/1.8/tk/root.rb:36:in `new'
        from (irb):2

  So I"m back to trying to get extconf.rb to work.  It usually fails
after not finding XOpenDisplay, which is curious as I built tcl/tk on
the same machine.

checking for t_open() in -lnsl... no
checking for socket() in -lsocket... no
checking for dlopen() in -ldl... yes
checking for log() in -lm... no
checking for tcl.h... yes
checking for tk.h... yes
checking for XOpenDisplay() in -lX11... no


  From reading the mkmf.log, I"m guessing it's not picking
/usr/X11R6/lib64 as the lib directory when it's trying to discover
libs.  It does try /usr/X11R6/lib, however.  I can't seem to figure out
a way to get it to add that search dir.  Guesses at adding with-x-lib
or with-x11-lib didn't seem to do it.

  Any help appreciated.  Thanks

Forrest
