error message (import)

In my package github.com/pierrre/geohash I try to create a slice of Point (https://github.com/pierrre/geohash/blob/master/geohash.go#L113-L116).

But gen returns an error:

➜  geohash git:(master) ✗ gen
geohash_benchmark_test.go:6:18: could not import github.com/Codefor/geohash (can't find import: github.com/Codefor/geohash)
exit status 1

or

➜  geohash git:(master) ✗ gen
cstest_test.go:6:2: could not import github.com/pierrre/cstest (can't find import: github.com/pierrre/cstest)
exit status 1
