The Symbols version is at least 6 times bigger than the Roots version
(7,790,644 vs. 51,211,964).
The version in Roots is almost twice the size of the one installed on
your system because darwinbuild builds universal binaries, which have
both ppc and x86 code, whereas your system is likely ppc-only.
