So if libmpfr-dev will make it work, I'm fine with that. What's weird is
that on a natty test machine where libmpfr1ldbl isn't installed, running
ldd on go1 gives "libmpfr.so.1 => not found", but also "libmpfr.so.4
=> /usr/lib/libmpfr.so.4", the latter apparently from libmpfr4.
I compiled this from source on a Lucid machine about a year ago; I had
installed libmpfr-dev to make it compile. I suppose I could recompile on
natty but I'd like to keep using the current binaries for a while...
