This does not help. Medium causes no change in behavior, whereas 'large;'
causes an early exit with a message about longs were expected to be 4
bytes, not 8. (But since I'm building 64-bit, longs are 8 bytes). Whereas
normally without either of those options, 5 shared libraries get built in
R, this reduces to two if {{{-mcmodel=large}}}.
I think the key to this is
http://blogs.sun.com/rie/entry/my_relocations_don_t_fit
I posted a log with the suggested debugging option
({{{LD_OPTIONS=-Dreloc,detail}}}) to
http://boxen.math.washington.edu/home/kirkby/r-2.10.1.p4-with-debug-
info.log.bz2
I think you will see, its not easy to debug.
