***********************************************************
  The existing menuselect.makeopts file did not specify
  that 'IMAP_STORAGE' should not be included.  However, either some
  dependencies for this module were not found or a
  conflict exists.

  Either run 'make menuselect' or remove the existing
  menuselect.makeopts file to resolve this issue.
