Courier broken?

[Socketd]

Hi

When trying to compile Courier 0.42.2 (plus GnuPG and Postgresql
support) on my 4.8-Release computer I get:

Compiling checkpasswordmd5.c
Compiling checkpasswordsha1.c
Compiling authpgsql.c
In file included from authpgsql.c:19:
authpgsql.h:8: libpq-fe.h: No such file or directory
gmake[2]: *** [authpgsql.o] Error 1
gmake[2]: Leaving directory
`/usr/ports/mail/courier/work/courier-0.42.2/authlib'
gmake[1]: *** [all] Error 2
gmake[1]: Leaving directory
`/usr/ports/mail/courier/work/courier-0.42.2/authlib'
gmake: *** [all-recursive] Error 1
*** Error code 2

Stop in /usr/ports/mail/courier.
*** Error code 1

Stop in /usr/ports/mail/courier.

Any ideas what's wrong? And any plans regarding updating Courier to
0.43?
