Zinf won't start on Linux

I downloaded the Zinf 2.2.1 and MusicBrainz 1.1.0 RPMs from the web
site, but when I run it I find that:

  [larsga@localhost larsga]$ zinf
  zinf: error while loading shared libraries: libmusicbrainz.so.2:
  cannot open shared object file: No such file or directory

and indeed the MusicBrainz RPM only installs libmusicbrainz.so.1 and
libmusicbrainz.so.1.1.

ldd tells me that I'm also missing libstdc++.so.4.

Where can I find these two shared libraries? I tried rpmfind.net, but
it hadn't heard of either.
