Subject: Re: [OMPI devel] trunk borked -- my fault
From: George Bosilca (bosilca_at_[hidden])

I used 2.64 for about a week on a bunch of machines. I never had
problems with it before...

After checking it turned out that autoconf 2.64 was freshly installed
on my Mac, so this might be a problem with autoconf 2.64 and MAC OS
X ... I'll go back to 2.63 until we figure out a way to solve these
problems.
