can find the package in default

[changchichung]

if go build by default(no modification aafter git clone) , there will be an error message

go build
postgresql_exporter.go:17:2: cannot find package "github.com/mc2soft/postgresql_exporter/metrics" in any of:
	/home/mnn/go/src/postgresql_exporter/vendor/github.com/mc2soft/postgresql_exporter/metrics (vendor tree)

	/home/mnn/go/src/github.com/mc2soft/postgresql_exporter/metrics
	/home/mnn/go/src/github.com/mc2soft/postgresql_exporter/metrics

so I have to manually copy the metric folder to /home/mnn/go/src/postgresql_exporter/vendor/github.com/mc2soft/postgresql_exporter/metrics and the go build .
is that normal ??

go get -u -v github.com/mc2soft/postgresql_exporter

This works for me.
