Is there a reason it's not there as a static library?

It should be doable, but in the distribution for RPM it appears that
the libtool scripts cause the static linking. So, I can patch the
libtool scripts and/or Makefiles so it won't use the static flag. I'm not
much of a libtool hero, but is there a cleaner way?
