Erreur lors de la configuration de kerberos5 à l'aide de macports

En essayant d'installer libmemcached via MacPorts, j'ai rencontré le problème suivant :

     libmemcached @0.40 +universal
--->  Computing dependencies for libmemcached
--->  Dependencies to be installed: cyrus-sasl2 kerberos5
--->  Configuring kerberos5
Error: org.macports.configure for port kerberos5 returned: configure failure: command execution failed
Error: Failed to install kerberos5

Il m'indique de consulter le journal pour plus de détails. Voici la dernière partie du fichier journal :

Il semble dire qu'il manque ncurses . Il semble cependant qu'il soit là, puisque si je lance port installed Je les vois :

ncurses @5.7_0
ncurses @5.9_1 (active)
ncursesw @5.7_0

Des idées sur la manière de contourner cette erreur ?
