E: Unable to locate package libpq-dev

The pg_config program: it is usually installed by the libpq-dev package but sometimes it is not in a PATH directory. Having it in the PATH greatly streamlines the installation, so try running pg_config --version: if it returns an error or an unexpected version number then locate the directory containing the pg_config shipped with the right libpq version (usually /usr/lib/postgresql/X.Y/bin/) and add it to the PATH:

export PATH=/usr/lib/postgresql/X.Y/bin/:$PATH
