Diane,

The missing symbols are

% objdump -x lib/libgfortran.so | grep GCC_4.6.0 | awk '{print $5}' | sort

__addtf3@@GCC_4.6.0
__divtf3@@GCC_4.6.0
__eqtf2@@GCC_4.6.0
__floatditf@@GCC_4.6.0
__floatsitf@@GCC_4.6.0
__floatunditf@@GCC_4.6.0
__getf2@@GCC_4.6.0
__gttf2@@GCC_4.6.0
__letf2@@GCC_4.6.0
__lttf2@@GCC_4.6.0
__multf3@@GCC_4.6.0
__netf2@@GCC_4.6.0
__subtf3@@GCC_4.6.0
__unordtf2@@GCC_4.6.0

It looks like we may be able to grab some of these from libc/softfloat:
getf2.c, gttf2.c, letf2.c, lttf2.c, netf2.c.

It looks like we might be able to grab a few more from NetBSD:
eqtf2.c and unordtf2.c
