  # Two patches that fix build problems:
  # 1. Don't hardcode OpenSSL location in imap Makefile. Homebrew-specific, so
  #    not submitted upstream. Submitted upstream to chappa@gmx.com.
  # 2. #ifdef DEBUG for stray use of global debug level var in web-alpine LDAP
  #    module. Submitted upstream to chappa@gmx.com.
