r22365 wasn't quite right -- Libtool 2.2.6b ''does'' report the "b" in

the --version output (ugh!).  So fix it so that if there are letters
in the release number, don't use -lt and -gt to compare; just print
"we found the wrong version" (don't try to determine if it's higher or
lower).

This commit fixes ompi's make_dist_tarball -- I'll let Ralph adapt for
the ORTE tarball script.

This commit was SVN r22366.
