Setkey and some other binaries in ipsec-tools are unnecessarily linked to libcrypto and other libraries (gssapi, krb5 and so on). Only racoon needs to be linked to these libraries.
This problem was fixed in RHEL-4 by adding -Wl,--as-needed to LDFLAGS but unfortunately although the patch is still applied the change is overwritten by autoconf run. So this is a regression against RHEL-4.
