[libvirt] broken pipe?

Wed Dec 3 22:47:11 UTC 2008

Thanks for the tips.
Next batch of issues...

1. while still trying to build manually... Any estimation on when/if 0.5
will make it to F10?

2. I'm using git, not cvs. Are these error in autobuild.sh of any
significance?
autopoint: *** cvs program not found
autopoint: *** Stop.

3. the blocking one - neither 0.5 tag nor head can autobuild or autogen.
Both fail with:
configure: creating ./config.status
config.status: error: cannot find input file: Makefile.in
since there are some other messages in the output, I've attached below the
full output in case it is relevant.

Thanks,
   Itamar
