It looks like the output from libtool trying to build redland-db-upgrade
but seems to have lost all link arguments.    Can you include a full
configure run + at least the last 10 lines of the make that fails?

I'm not familiar with slackware linux but since libpq.so.4 is not
installed in the library search path (i.e. is not in /etc/ld.so.conf) it
thus needs the extra runtime link args that you quoted from the pg_config:

LDFLAGS = -Wl,-rpath,/usr/local/pgsql/lib

However I redland's configure does not use those LDFLAGS, aka
pg_config --ldflags, it just invokes pg_config like this:

  LIBS="$LIBRDF_LIBS -L`$PG_CONFIG --libdir` -lpq"
(and later)
  LIBRDF_LIBS="$LIBRDF_LIBS -L`$PG_CONFIG --libdir` -lpq"

maybe those lines should be something else?
