[R] R installation on Linux/PPC with tcltk support

[Ryan Golhar]

I'm trying to install R on an IBM P570 running Redhat Enterprise Linux 
v4.  When I run ./configure, I see:

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
checking tcl.h usability... yes
checking tcl.h presence... yes
checking for tcl.h... yes
checking tk.h usability... yes
checking tk.h presence... yes
checking for tk.h... yes
checking whether compiling/linking Tcl/Tk code works... no


I have the tcl and tk rpms installed and the configure script does find 
them properly.  Why can it not compile/link Tck/Tk code?
