FTR, I noticed that Fedora does build a libgmp-enabled factor.
On F14, the factor binary is 52KB (vs. 32KB on debian unstable
x86_64 without the libgmp-hooked code).
The library itself weighs in at 380KB and has no dependency worth
worrying about:
$ ldd /usr/lib/libgmp.so.3.5.2
linux-vdso.so.1 => (0x00007fff76dff000)
libc.so.6 => /lib/libc.so.6 (0x00007fa5ba897000)
/lib64/ld-linux-x86-64.so.2 (0x00007fa5bae74000)
I have no strong opinion, either way.
