[R] Lost Tcl/Tk support

In prior versions, as recent as R-1.5.0pre (2002-04-08), Tcl/Tk support worked
just fine, with "configure" (no flags) finding /usr/local/lib/tclConfig.sh and
/usr/local/lib/tkConfig.sh.  In Monday's official release of R-1.5.0, Tcl/Tk
support now fails for me (under Solaris 2.6):
  checking for tclConfig.sh... no
  checking for tclConfig.sh in library (sub)directories... no
  checking for tkConfig.sh... no
  checking for tkConfig.sh in library (sub)directories... no
  checking for tcl.h... yes
  checking for tk.h... yes
  R is now configured for sparc-sun-solaris2.6

    Source directory:          .
    Installation directory:    /usr/local
    C compiler:                /res/local/bin/gcc  -g -O2
    C++ compiler:              g++  -g -O2
    FORTRAN compiler:          g77  -g -O2

    X11 support:               yes
    Gnome support:             no
    Tcl/Tk support:            no             <-----------------
    Readline support:          yes

    R profiling support:       yes
    R as a shared library:     no

Adding the --with-tcltk flag doesn't help, but adding flags:
does the trick.  (Note we have these files under both /usr and /res.)

This suggests to me that in the past 3 weeks, "configure" has lost its ability
to find the tclConfig.sh and tkConfig.sh scripts.
