Line 6 has umode_t on it:
typedef unsigned short umode_t;


While /usr/include/sys/types.h line 72 has:
typedef __mode_t mode_t;

proftpd's configure.in has:
AC_CHECK_TYPE(umode_t, mode_t)

And config.h.in has:
/* Define to `mode_t' if <sys/types.h> doesn't define. */
#undef umode_t

During configure we see:
checking for umode_t... no

The config.log contains:
configure:29869: checking for umode_t
configure:29894: gcc -c -O2 -Wall  -I/usr/include/postgresql conftest.c
>&5
conftest.c:122: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'ac__type_new_'
conftest.c: In function 'main':
conftest.c:126: error: 'ac__type_new_' undeclared (first use in this function)
conftest.c:126: error: (Each undeclared identifier is reported only once
conftest.c:126: error: for each function it appears in.)
conftest.c:126: error: expected expression before ')' token

So it seems to me that proftpd's configure script is broken somehow.
