working cisco vpn client for FC4?

[Robert P. J. Day]

  is there a vpn client that will build and install cleanly under FC4?
the (relatively recent) tarball someone just shipped me fails to
compile, and earlier versions of the vpnclient apparently need a patch
for one of the source files (interceptor.c).

  is there a client that builds/installs cleanly with FC4?  if not,
what's the magic incantation these days?  thanks.
