==> Rescuing build...
It looks like an autotools configure failed.
Gist 'config.log' and any error output when reporting an issue.

When you exit this shell Homebrew will attempt to finalise the installation.
If nothing is installed or the shell exits with a non-zero error code,
Homebrew will abort. The installation prefix is:
