Hi, how install postgres an openacs in diferent server.
The problem is, install database in server1 no problem, all correctly, both, install tcl in server2 no problem, install aolserver in server2 no problem, install nscache in server2 no problem, install NSPOSTGRES in server2 have problem.
You should install postgresql-client and postgresql-dev packages, assuming your server is debian linux. nspostgres requires some postgresql libraries to compile, and you need the client to access the postgresql server.
