In the VPP Meeting yesterday (10/18/2016), Dave Wallace reported having
issues compiling VPP in a Vagrant VM running Centos. The thought was it
might be a MAC issue. I was able to reproduce on a Fedora 24 host. Dave,
let me know if this is not the same issue you were seeing. I created Jira
https://jira.fd.io/browse/VPP-504 to track the issue.

Details:
I created a new vpp sandbox and ran vagrant vpp image with CentOs. The vpp
build failed in the CentOs Vagrant VM as follows:

=> default: make[5]: Leaving directory `/home/vagrant/git/vpp/build-r
oot/build-vpp-native/vlib-api'
==> default: make[4]: Leaving directory `/home/vagrant/git/vpp/build-r

==> default: make[3]: Leaving directory `/home/vagrant/git/vpp/build-r
oot/build-vpp-native/vlib-api'
==> default: @@@@ Configuring vnet in

@@@@
==> default: autom4te: cannot open autom4te.cache/requests: Permission

==> default: aclocal: error: echo failed with exit status: 1
==> default: autoreconf: aclocal failed with exit status: 1
==> default: make[2]: Leaving directory `/home/vagrant/git/vpp/build-root'
==> default: make[2]: *** [vnet-configure] Error 1
==> default: make[1]: *** [install-rpm] Error 1
==> default: make[1]: Leaving directory `/home/vagrant/git/vpp/build-root'
==> default: make: *** [pkg-rpm] Error 2


As a quick test, I added 'sudo' to the 'aclocal' and 'automake' and it
builds. I don't like spraying 'sudo' everywhere so this is just a work
around while I am still investigating.
