Libguestfs - Jan 2014 - Re: libguestfs build fails with: /usr/lib64/golang/pkg/linux_amd64/libguestfs.org/guestfs.a -- no such file

I'm on libguestfs Fedora git master branch:

  $ git log | head -1
  commit 8eb1aa2406632eb4202bbd976459334854295a77

  $ yum-builddep libguestfs

  $ fedpkg local


Results in:

There's no such file as guestfs.a in the above said directory:
=========  $ tree /usr/lib64/golang/pkg/linux_amd64/libguestfs.org/
  /usr/lib64/golang/pkg/linux_amd64/libguestfs.org/
  └── guestfs

  1 directory, 0 files
=========
What am I missing?

Thanks in advance.

I believe this happens if you have golang-guestfs installed at the
same time that you try to compile things locally.  It's a serious
design flaw in golang that the language is resistant to being properly
packaged.  (There is a bugzilla thread on this topic, but I can't find
it at the moment ...)

Indeed -- once I removed the golang-guestfs package, and re-issued
a local build, it goes through just fine:

  $ git log | head -1
  commit 8eb1aa2406632eb4202bbd976459334854295a77

  $ fedpkg local
