Hi Jeff,
 
I thought that the problem mentioned in the NEWS was only for Cray systems. I just checked ticket #1189 and this is exactly my case :-)
 
Thanks a lot !

Subject: Re: [OMPI users] configure script: Fortran 77-90: $LDFLAGS nothonored when checking whether gfortran and gfortran compilersare compatible: bug ?

Sorry for the delay in replying.

Looks like this was fixed already in OMPI 1.2.5.  So if you upgrade to 
1.2.6, you should be good.  1.2.7 should be out Real Soon Now, too.
