Well, it needs to be set to the path of the directory containing
the PgSQL libs or headers (that's probably what you meant).
With a standard PgSQL install from source and sh, you should do
the following:

export POSTGRES_INCLUDE=/usr/local/pgsql/include
export POSTGRES_LIB=/usr/local/pgsql/lib

If you're running a variant of csh, do:

setenv POSTGRES_INCLUDE /usr/local/pgsql/include
setenv POSTGRE_LIB /usr/local/pgsql/lib

Note that to install a DBD, you need to install DBI (or at least, to
use the DBD - I'm not sure if it's a preinstall requirement). You
can get DBI from CPAN, just like DBD::Pg

Just a note - when you get an error message, pay attention to what
it says. If you'd have diagnosed the problem with the original
install of DBD::Pg 0.95, you wouldn't have wasted time with the
other (old, possibly broken/buggy) packages of DBD::Pg. Error
messages are supossed to be informative.
