When cyrus-sasl2 builds, it uses the little shell script /usr/bin/krb5-config with the args. "--libs gssapi" to get the list of libraries to link against. This doesn't return "-lgssapi_spnego" in the list. (The list can be changed by editting line #96 of /usr/bin/krb5-config.) Nothing seems to link against "-lgssapi_spnego", so it's a mystery to me how it ends up using it? (Maybe others with knowledge on how FreeBSD loads libraries can explain it. The library is listed in /etc/gss/mech.) GSS_C_NT_HOSTBASED_SERVICE is defined in the file gss_names.o in "-lgssapi", which is at the beginning of the list of libraries returned by "krb5-config --libs gssapi". I'm hoping that someone who understands how libraries get loaded can solve the puzzle, but barring that, you could try added "-lgssapi_spnego" to line #96 of /usr/bin/krb5-config in front of "-lgssapi" and see if that gets things to load properly? Not much help, but I don't know how to test this stuff, rick
