From what I understand, on Unix there is a misleading error of "File does not exist" when loading a shared module, when dependencies of such a shared module don't exist. It may also be a case here.

An obvious dependency that's missing is Postgresql client libraries. You should install Postgresql to attempt to solve this problem.
