Please follow the instructions to report this bug at: 
https://github.com/mxcl/homebrew/wiki/new-issue
It looks like an autotools configure failed.
Consider re-running the install with '-vd' to keep 'config.log' around:
    brew install -vd gprolog
Gist 'config.log' and any error output when reporting an issue.
Remember to include your config information: brew --config

Also try:
  `brew doctor` to check your setup for common problems.
  `brew missing` to check installed packages for missing deps.
