On Debian system you will need following packages installed to use RServ.
If you don't have compiler installed, you will need that too.

libecpg3
libdbd-pgsql
postgresql-client
libpgperl
libdbd-pg-perl
postgresql-dev
postgresql

If you have postgresql-dev 7.3.4-[78] (and possibly others), you won't be
able to compile rserv trigger in lib directory. This is due to missing
/usr/include/postgresql/server headers (Debian BUG #215683). I copied mine
from 7.3.3-1 version.
