While trying to install libmemcached via MacPorts, I hit the following issue:

     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

It tells me to look in the log for details. Here's the last bit of the log file:

:info:configure checking for setupterm in -lcurses... no

:info:configure checking for tgetent... no

It seems to say it's missing ncurses. Looks like it's there though, since if I run port installed I see these:

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

Any ideas on how to get around this error?
