有谁在windows下装过GSSAPI模块吗？

因为要装Authen::SASL，perl makefile.PL的时候显示
[GSSAPI mechanism]
- GSSAPI           ...missing.
==> Auto-install the 1 optional module(s) from CPAN? [n]
于是去安装GSSAPI，但是perl Makefile.PL --help，显示
(1) --gssapiimpl /bla/local/heimdal
  This tells me where to look for your installed
  GSSAPI installation MIT or Heimdal.
  This must be the directory that contains
  the ./bin/krb5_config utility.
请问这个在windows下怎么处理？谢谢！
