[Help-gnu-radius] configure --with-postgres on debian 2.2 (potato)

[Nicholay P. Chuprynin]

Hello, All!

I have troubles compiling gnu-radius-0.96 with postgres support on my
debian potato system.
Then I use configure --with-postgres the configuration fails with the
following:

checking for -lpq... checking for PQconnectStart in -lpq... no
checking for PQconnectStart in -lpq... (cached) no
no
configure: error: -lpq not found

Note that I have libpgsql, libpgsql2 and postgresql-dev installed (from
.deb packages).
I tried to explicitly set the --with-include-path= and
--with-lib-path= as suggested in README, but without success.
If someone has similar setup working, please help.
