I think the error may be reported elsewhere than what was pasted in.
Could you provide a full configure log?

BTW: DDOS has made github inaccessible for most of today, at least
from where I am (US East Coast).  I'm currently unable to access
github, and that is also likely the cause for the Travis CI build
errors.
