You must have GNU autoconf, automake, and libtool installed to build
the developer's version of LAM/MPI.  You can obtain these packages
from ftp://ftp.gnu.org/gnu/.

It seems that the execution of "$rac_progs" has failed.
I am gonna abort.  :-(

This may be caused by an older version of one of the required
packages.  Please make sure you are using at least the following
versions:

GNU Autoconf 2.57
GNU Automake 1.7.8
GNU Libtool  1.5
