Why, because no-one uses ports?

The specific command that fails is in the PR, to whit:
cc -o conftest -O2 -pipe -g -DLDAP_DEPRECATED -fno-strict-aliasing -I/usr/local/include -I/usr/local/include/db41 -L/usr/local/lib -pthread conftest.c -L/usr/local/lib -L/usr/lib -lgssapi -lheimntlm -lkrb5 -lhx509 -lcom_err -lcrypto -lasn1 -lroken -lcrypt

where, in this instance, conftest.c is something like (extracted from the configure script from evolution-data-server):

/* contentes of confdefs.h, whatever that is, probably at least: */
#include <krb5.h>
/* end confdefs.h.  */

/* Override any GCC internal prototype to avoid an error.
  Use char because int might match the return type of a GCC
  builtin and then its argument prototype would still apply.  */
#ifdef __cplusplus
extern "C"
char krb5_init_context ();
main ()
return krb5_init_context ();
 return 0;

(fetchmail uses a conftest with a call to gss_check_version(), but the result is the same.)

And the cc fails with 
/usr/lib/ undefined reference to `MD2_Init'
/usr/lib/ undefined reference to `MD2_Final'
/usr/lib/ undefined reference to `MD2_Update'

as reported in the PR.

It doesn't do this on my system any more, because I've fixed it with the patch attached to that PR.
