[Lazarus] Cannot load libpq.so

[Leonardo M. Ramé]

Hi, I've installed PostgreSql from sources on a Linux machine, it's
installed on /usr/local/pgsql. It's libraries are in
/usr/local/pgsql/lib, and I updated my /etc/ld.so.conf to look there,
but still, when I run a simple testing app written with lazarus I'm
getting this:

EInOutError : Can not load PostgreSQL client library "libpq.so". Check
your installation

What can be happening?.
