[OpenAFS] Failure to build OpenAFS 1.6.1a

[Michael D. Norwick]

Good Day;
I am trying to compile OpenAFS 1.6.1a from a tarball downloaded from
openafs.org last Thursday.  I am using Slackware 13.37,

Linux rainey 2.6.37.6 #3 SMP Sat Apr 9 22:49:32 CDT 2011 x86_64 AMD
Phenom(tm) II X4 965 Processor AuthenticAMD GNU/Linux

and G.C.C.,

I installed Kerberos 1.7.1 from a SlackBuild and it built and configured
without error.  The text of the error message follows;

afscp_util.c: In function '_GetSecurityObject':
afscp_util.c:160:5: error: 'krb5_creds' has no member named 'keyblock'
afscp_util.c:199:21: error: 'krb5_creds' has no member named 'keyblock'

make[1]: *** [build] Error 2
make[1]: Leaving directory `/usr/src/openafs-1.6.1a'

Am I lacking a patch for OpenAFS or Kerberos or something?  I did
./configure --with-krb5=/usr/kerberos
--with-krb5-include=/usr/kerberos/include --with-krb5-lib=/usr/kerberos/lib.

Thank You,
Michael
