How to find all dependents of go?

[Christoph Iserlohn]

Hi,

because of:
https://groups.google.com/forum/#!msg/golang-dev/MEATuOi_ei4/nl8jrt9YEwAJ
i would like to bump the revision of all dependents of go to force a rebuild
with version 1.5.3.

But
$ port dependents go
returns
go has no dependents.
which is clearly wrong. I have several ports depending on go installed, e.g.:
$ port installed go-tools
The following ports are currently installed:
  go-tools @65b5a8eca7a871e7c1d99722e4a43a4a6e32ebe0_0 (active)

No luck with port search either:
$ port search --exact --depends_lib --depends_build go
No match for go found

Any suggestions?
