I installed and built the Tcl/Tk source RPM, and now the file that R wants
is there.  By skipping the "modules" packages, the build gets all the way
to the end.

"make check" fails rather quickly:

    running code in `base-Ex.R' .../bin/sh: 51598 Illegal
	instruction(coredump)
    make: 1254-004 The error code from the last command is 1.

When I try to run R, I get the opening info and then a "> " prompt.
I can type simple commands like help(), but whenever I type q() to
quit, I get a coredump.  This is consistent with what I saw earlier when
the build was trying to load "modules".  The stack trace in the coredump
contains this:

Segmentation fault in spin_lock_global_ppc_mp at 0xd0106644 ($t1)
0xd0106644 (spin_lock_global_ppc_mp+0x24) 7ce5192d     stwcx.   r7,r5,r3
(dbx) where

exit(??) at 0xd0177c40
Rstd_CleanUp(0x3, 0x0, 0x1), line 529 in "sys-std.c"

It almost looks like R is working OK until it calls "exit", and then it
blows up.
