kerberos 1.3.1 and sudo

[Andrew Hall]

Greetings,

This might be a little OT and if it is I apologize.  I am attempting to
compile kerberos and sudo on RedHat 8 and gcc 3.2.  Kerberos compiles
fine, and I install to a tmp DESTDIR.  I then point sudo's configure at
the newly installed kerberos libs and I get the following error with two
different versions of sudo (latest: 1.6.7p5 and 1.6.3):

The reason I post here is that I get the same error with both versions
of sudo, so I figured I start here.  Does anyone have an idea as to what
I am doing wrong? 

Thanks.
