You can do a couple of things, The best would be probably
make a slave port from krb5 that defines KRB5_KRB4_COMPAT
and then make your port depend on the krb5 slave port.
Or you could depend on %%KRB4%%bin/krb524init since it's only
installed if KRB5_KRB4_COMPAT is defined and print a message
in pre-XXX if it's not found but krb5 is installed.

For an example take a look at graphics/evince and how it depends
on graphics/djvulibre or graphics/djvulibre-nox11 and how djvulibre[-nox11]
work.

Cheers,
Michael
