[Rd] R-beta: configure problem (tcltk) on 64 bit Red Hat EL

[Prof Brian Ripley]

Yes, the R-admin manual warns of this.

It is a problem with your particular OS, as e.g. FC3 does

checking for tclConfig.sh... no
checking for tclConfig.sh in library (sub)directories... 
/usr/lib64/tclConfig.sh
checking for tkConfig.sh... no
checking for tkConfig.sh in library (sub)directories... 
/usr/lib64/tkConfig.sh

and that config file has

# Additional libraries to use when linking Tk.
TK_LIBS='-L/usr/X11R6/lib64 -lX11 -ldl  -lieee -lm'

Unfortunately you have removed the crucial parts of where your configure 
got the configuration info from.
