building psqlodbc-07.03.0260 failed: "no suitable ODBC driver manager found"

hi,all:

I tried to build psqlodbc-07.03.0260 on FreeBSD 5.4(i386 machine) but
failed.

When I run "./configure --with-unixodbc" in the psqlodbc source dir and the
following was given:

checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... no
checking for mawk... no
checking for nawk... nawk
checking whether make sets $(MAKE)... yes

checking whether gcc accepts -g... yes
checking for gcc option to accept ANSI C... none needed
checking dependency style of gcc... gcc3
checking for SQLGetPrivateProfileString in -lodbcinst... no
configure: error: unixODBC driver manager not found

I have already installed unixODBC-2.2.11 which is working well on my
machine.

But ,what is the problem of building psqlodbc and how can i fix it?

Yours,
Lestat
