Compiling pgadmin3-1.14.1 on open BSD 5.0

pgadmin3-1.14.1 won't build under the following:

openbsd 5.0

postgresql9.1.2 from source with: ./configure --with-perl --with-openssl
--with-includes=/usr/local/include --with-libraries=/usr/local/lib
--enable-shared
--with-libxml --with-libxslt --enable-nls="fr-es-pt-de"

postgresql is installed in /usr/local/pgsql (/bin /lib /include etc...)

wxWidgets was installed from obsd package. So far nothing wrong with
widgets.

To compile pgadmin, I used:
./configure --with-pgsql=/usr/local/pgsql

The result is the following:
[...]
checking for libpq-fe.h usability... yes
checking for libpq-fe.h presence... yes
checking PostgreSQL in /usr/local/pgsql... failed
configure: error: you must specify a valid PostgreSQL 8.4+ installation
with
--with-pgsql=DIR

when I do grep "libintl" * in config.log I get:

/usr/bin/ld: warning: libintl.so.5.0, needed by
/usr/local/pgsql/lib/libpq.so.5.4, not
found (try using -rpath or -rpath-link)
/usr/local/pgsql/lib/libpq.so.5.4: undefined reference to
`libintl_bindtextdomain'
/usr/local/pgsql/lib/libpq.so.5.4: undefined reference to `libintl_dgettext'
/usr/local/pgsql/lib/libpq.so.5.4: undefined reference to `libintl_gettext'

However libintl.so.5.0 is in /usr/local/lib, is loaded at boot time, as
showed in
/var/run/ld.so.hints

AND in the config.log file for compiling postgresql, I get:

configure:28380: checking for libintl.h
configure:28387: result: yes

My installation of pgsql works fine. I just can't compile pgadmin.
There is an openbsd package for pgadmin, but I would have to install
postgresql from package too, and openbsd places it in some odd place, also
I don't the latest version.

My guess is that I need to tweek my pgsql configure options, I just could't
find
how.
